Its stated that like charges repel,then why do protons in the atom's nucleous dont get repelled?

The nuclear strong force keeps the nucleus together...Otherwise, you would be right.

Atoms don't get pulled around by electrons. The electrons orbit around the nucleus of an atom. The electrostatic attraction between the protons in the nucleus and the electrons is what keeps the electrons orbiting. When atoms form molecules, it is electrons that hold the atoms bonded to one another... electrons are "shared" by the various nuclei in the molecule. In other words, the electron orbits (orbitals) from neighboring atoms overlap, and the electrons can move freely within the system of overlapped orbitals.

Very good question. When you get to the nano level you do not actually talk of objects touching one another, but rather interacting with one another. When two atoms get very close to one another the the electrons repel one another strongly as predicted by Coulomb's Law ( F=k(q1*q2)/r^2). This law also shows why this is only important a close range with atoms. This is because at distance fairly far away the atom is viewed as an electrically neutral particle be cause the protons counter act the electrons. At close distances however the electrons get much closer to one another than the protons do and so that r value is relatively much smaller for the electrons so the force repelling is great. The name given this particular phenomenon is Van Der Waal Forces. \n\nThis same types logic is followed even into the subatomic world.\n\nOh, I missed the real question. You are talking math not physics. Algebra can not effectively deal with infinite. To deal effectively with infinity it is best to deal with calculus where they get around the subject by saying the limit x approaches infinite, or the limit as x approaches zero.  Now it is best to realize that while math is a great tool for describing reality it is a man made invention that reality does not need in order to exist. Due to the above answer I have explained that in the real world objects do not actually touch. There are however mathematics available that get around your problem. One area of math is called infinite series usually studied in Calculus II. Note: my only real interest in math is to solve physical problems, so a true math person would probably be able to give you a better answer on the math end of the question.

Atoms are neutral due to the balance between the number of \nelectrons and protons in the nucleus. In some cases, they are not balanced due to the absence one or more electrons in the orbit and they are called Ions.

it holds the nucleus together. there is a another force acting that is stronger than the repulsion of the protons for each other known as strong nuclear force

The reason for that is simple.\nAll fundamental forces work on objects carrying a specific type of charge, as in electrical charge, weak charge, colour charge....\nThe charge for gravity is mass. And unlike other of these charges it has only one type (maybe predominantly) - positive mass. For that reason, there is no chance for masses to cancel each other out like when you have a positive charge and a negative charge and together the objest (an atom, for instance) is neutral electrically\nI'm not sure about the weak charge though. Weak forces have a limited range because the bosons that carry them are heavy and can't go far, because of uncertainty (I'm not going into this deeper)\nBottom line: gravity works long range because all masses add up and not cancel each other out.

Consider that one electron will repel another electron (-ve does not attract -ve), each bond between a carbon and hydrogen is cased by a pair of electrons (2 electrons) so you have a total of eight electrons... this results in neutralising the charge on all the atoms.\n\nCarbon has 2s1, 2s2, 2p2 electrons which means it is theoretically 4 electrons short of its closest nobel gas (nobel gases are neutral).\nHydrogen has 1s1 electrons which means it is theoretically 1 electron short. Note that there is no p orbital in first row of periodic table.\n\nAs such each hydrogen shares its sole electron with the carbon, donating a total of 4 electrons, hence 4 hydrogens.\nThe Hydrogens get their electrons from the carbon, the carbon has 2s2 and 2p2 electrons, totalling 4 to share, 1 to each hydrogen... we do not count the s1 orbital because it is unlikely to operate in forming bonding.\n\nNow each pair repels eachother so they are furthest apart, if we do the mathematics...\nblah blah...\nWe end up with an optimum angle of 107.5 degrees between eah hydrogen, any more than that and a different hydrogen will repel it back, and likewise if less. this forms a 'tetrahedral' shape.\n\nIf you were to switch a hydrogen with another element... say chlorine, to produce CH3Cl (Chloro-methane) then the hydrogens (being the smaller atoms with less electrons) will be pushed further from the chlorine which will tend to determine the molecule's appearance. Ch3Cl is not a perfect tetrahedral as its angles will not equal 107.5, but we still call it that for simplicity's sake.\n\nI recommend that for further information do a search on the following phrases:\n\nVSEPR\nValence Shell Electron Pair Repulsion theory\nMolecular geometry\nMethane\nOrganic Chemistry

The charge of a proton is equal in magnitude to the charge of an electron, but a proton has a positive charge and an electron has a negative charge.  The number of protons in an atom is equal to its number of electrons, so the atom has no net charge.

Electrons have a negative charge and are held in the atom by the positively charged nucleus.  The further away from the nucleus that the electrons are, the easier it is to remove the electron.

The cell is still made up of many atoms, thats the only irrefutable link there. And the atom is not the elementary essential of matter, if by elementary essential you are referring to the smallest constituent of a matter. Atom is made of of sub-particles: protons, electrons, neutrons, quarks... And these are further made up of smaller sub-particles (our knowledge are always limited). Proton and nuetron have masses and volumes. Doesnt that mean they are matter too?

No. Protons don't flow. Electrons can be removed from the atom, but protons can't (well, unless nuclear reactions are taking place).\n\nI'm assuming you're talking about electricity flow? Instead of electron flow, you can use "space" flow, that gap that "travels" like a wave in the opposite direction of the electron flow.

Even a simplified answer to this is very complicated, so bear with me...\n\nHopefully by now you've learned in school about how everything is made of atoms, and that atoms in turn are made up of smaller particles such as protons, neutrons and electrons.\n\nNow ask yourself:  How come I can stand on the ground?  Why don't I fall straight through the ground to the center of the earth?  What keeps gravity from "mushing" everything together, even electrons and protons?\n\nThere are four Fundamental Forces that we know of in the Universe.  The Fundamental Forces are the "rules" by which all the matter in the Universe interacts with each other.  The four that we know of are:  Gravity, the Electromagnetic Force, the Weak Nuclear Force and the Strong Nuclear Force.\n\nAll the matter in the universe has Gravity as a force, and Gravity is always a "pulling" force; things are always attracted to each other by Gravity.  Gravity is also a very long-reaching force; gravity holds the planets in orbit around the sun, holds the sun and other stars together in a galaxy; and Gravity even acts between other galaxies.  Gravity is a force that reaches all the way across the Universe.\n\nThen there's the Electromagnetic Force.  This is what makes electricity and magnets work.  The Electromagnetic Force (or EM for short) is actually much, much stronger than Gravity, but it works over a much, much shorter distance than Gravity does.  EM is also a "two-sided" force; there's a positive and a negative.  In magnets they're called "north" and "south."  Two charges that are opposite -- positive and negative -- attract each other, while two charges that are the same -- say, negative and negative -- repel, or push each other apart, like when you put the south poles of two magnets together, they want to push apart.\n\nAtoms are made up of protons (which have a positive EM charge) and electrons (which have a negative EM charge).  The protons are all at the center of the atom, while the electrons spin around the outside, making an electron "shell."  Since two things of the same charge repel each other, when two atoms come near each other the negative charges of their electrons push them away from each other.\n\nSo the reason you stand on the ground, why Gravity doesn't pull you down to the center of the earth, is because the electrons in the atoms of your feet are pushing against the electrons in the atoms in the ground.  And since the EM force is much stronger than Gravity, the EM force holds you up and keeps you from "mushing" into the ground.\n\n...Okay, what does this have to do with black holes?  I'm getting to that.\n\nMaybe you've learned in school that our solar system -- the earth, the other planets and the sun -- started out as a huge cloud of gas and dust.  Over billions of years Gravity pulled the atoms in this cloud closer and closer to each other, until they started condensing ("mushing" together) to form the earth, the planets and the sun.\n\nThe sun, you know, is not a solid ball, like the earth is.  It's a huge ball of gas, mostly hydrogen.  So, why doesn't Gravity mush the sun smaller until it becomes a solid ball?\n\nThe reason why is the same reason the sun shines.  The sun is about a million miles across.  That's a really, really huge amount of hydrogen.  Now, Gravity does pull the gas on the surface of the sun down towards the middle; so the atoms on the surface of the sun "fall" down towards the center.  That's half a million miles, which is a long way to fall for anything, even a hydrogen atom.  So when the hydrogen gets to the center, the weight of all the gas above it is so huge, that the atoms get pushed together really hard; hard enough to overcome the negative electrons on the outsides of the atoms.  The hydrogen atoms get "scrunched" together to form a different kind of atom --

Hm.  Okay.  Here's some stuff about atoms to get you started:\n\nJust like all things are made of atoms, all atoms for the most part are made up of the same three parts.  Protons, neutrons, and electrons.\n\nProtons and neutrons are comparatively really heavy.  Pretty much all the weight of an atom comes from these guys.  Because they're heavy, they don't move around a lot unless the whole atom is moving.  Instead they stick together in the center of the atom (also called the nucleus).\n\nElectrons live very different lives.  Unlike protons and neutrons, they are not only light but comparatively large.  They buzz around the nucleus like planets around a star... or perhaps more like beach balls around a sack of marbles.  A lot of chemistry has to do with electrons zipping around, being attracted to one thing or another... or more likely to several things at once.\n\nAnother important thing to know about the parts of atoms is their charge.  The charge in these parts come from the electric force, which (if you can imagine it) is a billion billion billion billion billion billion times stronger than gravity (yes, that's a one followed by 36 zeroes).  The electric force is also involved with electricity that we use in our houses and the like.\n\nThe pro- in proton comes from its positive charge.  To make things easy for themselves scientists just decided to say a proton has a +1 charge.  The neu- in neutron comes from it being neutral.  It has zero charge.  Electrons have the opposite charge of protons, so they have a -1 charge.  Pretty straightforward.\n\nAnd here's where things get interesting.  The name we give an atom (like helium or uranium or whatever) depends ONLY on the number of protons it has.  So, for example, an atom with two protons is helium, no matter WHAT else its got.  Neutrons hang out in the nucleus with protons, where they add to the weight of an atom but don't do much else.  And the REASON all those electrons are buzzing around a boring nucleus instead of being off somewhere else is because all those negative charges like to be near all those positive charges.  And since the electric force is so incredibly strong, you can bet that just about everything you run into is going to have as close to a zero total charge as it can get.\n\nSo there you have it.  Atoms in a nutshell.  Hope that helps!

Yes it sort-of works for a hydrogen atom.\nYou do need to know about electric field attraction.\n\nthe attraction of charges pulls the electron in, the angular motion holds it from being pulled all the way.\n\nAlthough this model (planetary model) is wrong, it is amazing how close it comes considering that it is so far from what we believe to be true!!

Protons are positively charged particles.\n\nBetween protons there are two types of forces.\n\nOne is the electro-static repulsion between two protons.\n\nThe other is the gravitational force of attraction between the masses of protons.\n\nWhen two protons are separated by any distance,\n\nThe electro-static repulsive force is 1.29 x 10^28 times greater than the gravitational attraction between them.

Good question.  As you probably know ordinary atoms involve protons, neutrons, and electrons.  The muon plays absolutely no role in the structure of the atom.  In fact it is just one of many particles in nature that decay very quickly and don't seem to have any real purpose.  (although it is possible conservation of energy or momentum or something requires them)  It is interesting to note that muons have the same charge as an electron but a greater mass.  Muons are attracted to protons and can form atoms with muons circling around the nucleus instead of electrons.  Because of the muon's larger mass the muonium atoms are "smaller" than ordinary atoms.  Muonium atoms also don't last very long.  It is hoped that someday a particle theory (perhaps string theory) will explain why all these odd "useless" particles exist.

Atoms do not have a charge.\nIons have a charge (either plus or minus)
