I'm having trouble putting this in my own words. Any suggestions? Is there another name for "electron sea model?"
128284
In brief:  a model of metallic bonding in which cations are considered to be fixed points within a mobile 'sea' of electrons. \n\nAnother view could be from this definition: (Electron Sea Model) : The metallic bond consists of a series of metals atoms that have all donated their valence electrons to an electron cloud that permeates the structure. This electron cloud is frequently referred to as an electron sea. It might help to visualize the electron sea model as if it were a box of marbles that are surrounded by water. The marbles represent the metal atoms and the water represents the electron sea.\n\nIf you want to look at Electron sea diagrams, go to this URL:\n\nhttp://bouman.chem.georgetown.edu/statesofmatter/stelectron.htm

Four.\n\nThe first one is usually called "n" and it gives what people think of when they say "energy level".  It's also called the "principal quantum number", I think.\n\nThe next one is usually called "l" (el) and for a given energy level, it can be anything from 0 up to "n-1".  These correspond to what people sometimes call "shells", such as the s, p, d, f, etc. shell.\n\nThe next one is called "m" and is sometimes called the "sub-shell".  Each shell can have up to "2*l+1" sub-shells.  So an "s shell" (l=0) can have 1 sub-shell.  A "p shell" (l=1) can have 2*1+1=3 sub-shells, etc.\n\nThe final quantum number is called "s" or "spin".  For each sub-shell, this can take on one of two values, +1/2 or -1/2  in some books.  This means that only two electrons are allowed in any given sub-shell.\n\nSo for n=1, the only option is l = 0, which means further that m must be 1, with 2 choices for s.  This all means that the first energy level can only hold 2 electrons.\n\nFor n=2, l can be either 0 or 1.  For l =0, m must again be 1, allowing 2 electrons.  For l = 1, m can be as much as 3, each allowed to have 2 electrons.  So adding the 2 electrons for the l=0 subshell to the 6 allowed in the 3 possible subshells for l=1 (6 electrons we get a total of 8 electrons allowed in the second energy level.\n\nYou can continue on to get totals of 18 (2 + 6 + 10) for the 3rd energy level (n=3; l =0, 1, or 2;  and m = 1, 3 and 5, each with 2 electrons allowed).\n\nThis is where the numbers that correspond to "filled energy levels" come from in the periodic table.

Wow, that was a totally new term for me. I am glad you asked this question. It took me some time, but I finally found a "shipper" site that had a glossary, and here is how they define shippiness:\n\n'"ship also ship—Shipping is a general term for emotional and/or intellectual involvement with the ongoing development of romance in a work of fiction. Shipping can involve virtually any kind of relationship — from the well-known and established, through the ambiguous or those undergoing development, and even all the way to the highly improbable and the blatantly impossible. People involved in shipping (or shippers) assert that the relationship does exist, will exist, or simply that they would like it to exist. The term "ship" is said to have originated in X-files fandom, where it was used to describe fanfic about a romantic relationship between Mulder and Scully. Soon, people who supported this "ship" were calling themselves "shippers." These terms found their way to Harry Potter fandom, so someone who thought Ron & Hermione were meant for each other would call themselves a "R/H shipper." But it didn't stop there - people began forming clubs, using a metaphor of ships moving on the sea. Each has gained a strange and wonderful name, so the Ginny/Tom Riddle ship is called "The HMS Gin n' Tonic" and the Harry/Hermione club is called "The HMS Pumpkin Pie." More information on ships, and a lot of ship discussion, can be found on the Park at SCUSA"\n\nAnother term showing up a lot was "fanfic," meaning "fiction written by fans" of a particular show, story, etc.\n\nI just posted this when I saw your additional info. You are going to have to find "slashy" yourself. I am shipped and fanficked out, lol\n\nI hope this helps.

Basically, this is it -\n\nIn atomic physics, the Bohr model depicts the atom as a small, positively charged nucleus surrounded by waves of electrons in orbit — similar in structure to the solar system, but with electrostatic forces providing attraction, rather than gravity, and with waves spread over entire orbits instead of localized planets.\n\nThe Bohr model is a primitive model of the hydrogen atom that cannot explain the fine structure of the hydrogen atom nor any of the heavier atoms. As a theory, it can be derived as a first-order approximation of the hydrogen atom in the broader and much more accurate quantum mechanics.

My brine's awash with possible theories. I haddock a few answers, but they all turned out to be damp squids. It's the sea air, it fogs the senses. Time to stop carping on . Ah whelk, i'll say tartar. Nothing newt there then.

initailly it was believed that current flows from+ve to -ve. but actually its electrons moving from -ve to +ve. so it became - current flows from +ve to -ve (thoritically) electrons from -ve to +ve (actually)\n\nhope that answeres

Be careful with your statement.  The electrons do not act like both a wave and particle at the same time!  They act like one or the other.\n\nWhen you are not "watching" the electrons, they exhibit wave like behavior because they hit on the screen only in the spots that would correspond to a bright fringe for light.  But, that isn't the coolest part.  \n\nFirst: you can shoot one electron at a time, and each time, each electron will hit at a spot that would be a bright fringe, if you were to shoot light with the same wavelength through two slits.  Now, cover one of the slits and shoot one electron at a time, and the pattern will shift to that of a single slit diffraction. \n\nQuestion: How does the electron "know" if there are two slits or one slit, so that it hits the correct spot on the screen?  Answer: if there are two slits open, it goes through both slits on its way to the screen!  In essence, it interferes with itself!  This is what is known as the sum of histories, where the electron is said to take every path possible on its way to the screen.  \n\nOf course, you might object and say when I shoot a cannon ball into the air, it only takes one path: the parabolic curve.  So, why does an electron take every path and the cannon ball does not?  This is the essence of quantum physics: these bizzare happenings occur with the very small.  However, the sum of histories can still be applied to a cannon ball, but guess what?  All paths cancel except for the parabolic path it will always take on Earth.  For the electron, each path has equal probability, so they do not cancel, thus it goes through both slits at the same time.\n\nSecond: If you try to "watch" the electron go through both slits by using an instrument, the electron stops acting like a wave, and behaves like a particle.  It hits the screen like a particle should.  Stop "watching" it and the pattern goes right back to that of wave interference!\n\nIt's as if nature will not allow us to see such bizarre things.

IT could be diamagnetic according to electron configuration from Chemistry. But without specific formula I would say your best bet is e nomagnetic.

The Babel Fish.\n\n"The Babel fish," said The Hitch Hiker's Guide to the Galaxy quietly, "is small, yellow and leech-like, and probably the oddest thing in the Universe. It feeds on brainwave energy not from its carrier but from those around it. It absorbs all unconscious mental frequencies from this brainwave energy to nourish itself with. It then excretes into the mind of its carrier a telepathic matrix formed by combining the conscious thought frequencies with nerve signals picked up from the speech centres of the brain which has supplied them. The practical upshot of all this is that if you stick a Babel fish in your ear you can instantly understand anything said to you in any form of language. The speech patterns you actually hear decode the brainwave matrix which has been fed into your mind by your Babel fish.\n\n"Now it is such a bizarrely improbable coincidence that anything so mindboggingly useful could have evolved purely by chance that some thinkers have chosen to see it as the final and clinching proof of the non-existence of God. \n\n"The argument goes something like this: `I refuse to prove that I exist,' says God, `for proof denies faith, and without faith I am nothing.'\n\n"`But,' says Man, `The Babel fish is a dead giveaway, isn't it? It could not have evolved by chance. It proves you exist, and so therefore, by your own arguments, you don't. QED.'\n\n"`Oh dear,' says God, `I hadn't thought of that,' and promptly vanished in a puff of logic.

I posted a very similar question here not long ago (minus the farting bit)!!\nI asked if I was the only one that thought it was all 'tosh'\nI should have actually asked about ozone layers etc!\nHowever I did get a couple of very interesting answers that agreed with me, I hope you get the same response, I am sure it is all hogwash and I was very pleased to hear from others that were on the same wave length.

Danmergury is totally right.\n\nHere's a link to the periodic table:\nhttp://www.webelements.com/\nSo that you can see what he's talking about with the different groups having different charges.\n\nYou can think of it like this: \nThe atomic number (like 4 for Be) is the number of protons, as well as the number of electrons. So Be has 4 electrons. So you can think of adding a proton and electron each time you go to the next element on the periodic table.\n\nBut let's focus on the electrons. To count them up in Be, you start at H, then go over to He. Every time you reach the end of a row in the periodic table you have completed a shell. This makes elements stable and happy. But we have to keep going to get to Be. So you add another electron as you go past Li and finally you get to Be with 4 electrons.\n\nSo -- If you look at that periodic table, Be has those 2 extra blue electrons that are keeping it from being like He, which is a happy element. That last row is sometimes called the Noble Gases. All the other elements wish they were as cool as the noble gases. So Be is gonna get rid of it's 2 extra electrons to try to be like He.\n\nDoes that kinda make sense?\n\nIn a similar way, S is only 2 electrons away from being like Ar. So S tries to find 2 electrons that it can steal from another element so that it can be like Ar.\n\nGood luck with your classes!

The Bohr model is simply an easier model of the atom. Sure it has been proven that electrons are really a probability cloud centered around the nucleus, but try explaining that to a 6th grader. \n\nYour question could also be asked of Newtonian physics. Why do we teach it when Mr. Einstein's theory of relativity has proven it wrong? \n\nThe answer to that question and yours is basically...it's good enough :-P

Your analogy doesn't represent the problem at all.  \n\nWhen we say a particle is treated as a wave it refers to the particle actually not existing at any particular point.  It actually exists at all of points in some region with a certain probability (it is everywhere at once).

Sounds like the typical process of using electrolisis to separate H2O in to Oxygen and hydrogen. The hho is  another way to write H2O

Ok.....oxygen becomes O2-,Na becomes Na+,and F becomes F-.\nSo WHY????\nWell,a valence electron is an electron that has a full outer shell.We'll call it a shell since it looks like one(round,smooth),although it is actually the amount of electrons an atom's nucleus can hold within that orbit,like the Sun holds all the planets together,except this is like the Solar System on steroids.\n\nAnyways,when the atom has eaten its fill of electrons,bullying any other weaker atoms in its way to get its fill,it is satisfied when iit is 'full',meaning all its outer electrons are filled.No more,no less.Like with humans,too many electrons would be like an obese person;one would need to lose all that flab,and become normal-sized.Likewise,the atom would need to lose electrons to become stable.Also,too little electrons is like an anorexic person;needs to bulk up.So,the electron needs to gain more electrons to become stable.\n\nNow,the problem here is;some atoms are just naturally unstable.For example,sodium naturally has one EXTRA electron from that perfect stability.So,it REALLY tries to WORK OFF THAT EXTRA FATS,so to speak,to lose that extra electron,to be perfect.So,all it needs to look for now is somewhere to put that electron.\n\nLets look af Flourine.FLourine is REALLY anorexic;it has one electron less.So,what does it do?It asks sodium politely if it can have that extra electron.Sodium of course agrees,and they exchange.\n\nSee the problem here?If sodium and fluorine were natural before with their fatness and thinness,what are they now?They are called IONS;they have stable electron configuration,but have unnatural electron configuration.\n\nSo,all you need to do is look ad your good ol' Periodic table.Look under the same row of whatever element you want to choose and look at the electron configuration of the noble gas of that particular row.For example,neon has the atomic number 10.Say you want to find Oxygen,which has the atomic number 8.So,since neon is the perfect one,and oxygen wants to get to that number,oxygen need to GAIN 2 electrons.We call this ion O2-,since we take perfect as 0,and anything below that is -,and everything above it is +.Therefore,since Sodium is 11,it needs to LOSE one to become neon,since its easier to lose one electron and become neon's configuration than gaining 7 and becoming the noble gas of that row.So,sodium becomes Na+\n\nAs a general rule of thumb,the left side of the Periodic Table is +,and the right side is -.There exceptions however,which you have to memorise.So,does that answer your question?

Look at the acronym he uses -- hho.  What's another way to write that -- perhaps H2O -- which is water!\n\nThere have been many scams purporting to generate power by injecting water into a fuel supply, or a carburator, etc.  But they are SCAMS.  \n\nThe laws of thermodynamics make it impossible to get more energy out of a system than you put into it -- so you'd require more energy to electrolyze the water into hydrogen and oxygen than you could ever possibly get back by the recombination reaction, even in a perfectly designed system.
