Does anyone have the answers to the alien periodic table?

Are you referring to the exercise on this page:\nhttp://galileo.phys.virginia.edu/outreach/8thgradesol/PeriodicTable.htm\n\nI had never heard of that before (I teach chemistry); sounds like an amusing exercise! Only I can't see why they'd call Francium an element in group13 (IIIA) and period 4 when it is already a real element in group 1A, period 7! Good luck! I'm assigning Gas Law homework currently and have very little time, or else I'd do the exercise!

a long time ago I heard a really goofy song some guy made up of all the names of the elements in the periodic table. I don't have any idea who recorded it, but I bet it was from the 1960's or even earlier. Maybe you could try Googling that song and singing along until you learn it. (I learned the fifty states in alphabetical order by singing them in a song!)\n\ngood luck!

look up the periodic table...duh

With modern chemistry and quantum physics knowledge, we know 104 elements. \n\nAn element is defined by proton count, which in turn determines the number of electrons in orbit. Hence we know we aren't missing any elements in between, all numbers between 1 and 104 are known.\n\nThis leaves elements with proton counts of 105 or greater. The greatest difficulty in identifying these is that they are extremely unstable. The observer needs to be lucky and skilled to observe one of these superheavy elements before it decays.\n\nEven more so since these elements are produced by colliding heavy ions at high speed, creating lots of  energy at the collision. Capturing such an element and identifying its mass charge ration in a mass spectrometer or getting spectroscopical data that can be fitted to the theoretical energies one would expect is hard under these circumstances.

look it up on any periodic table - like the one linked below... good luck!

She was refering to the 21 cm Hydrogen line which is considered to be one of the best places to look for signals from aliens.\n\nHydrogen times π means that the frequency (1.420 GHz) of the Hydrogen line was multiplied by π by the aliens who sent another signal.  The Movie was called Contact BTW and is one of the less inaccurate movies out there.\n\nEDIT: Got hydrogen line frequency wrong.

When we have answered the question "Do aliens exist?" we certainly would be able to answer them too ;-)

Why don't you open a periodic table and answer them yourself?

The periodic table as of Oct. 2005 according to IUPAC shows 111. But the elements with atomic numbers 112, 114, and 116 have been reported but not have not been fully authenticated as of September 2003 (Pure Appl. Chem. 75(10), pp. 1601-1611, 2003).

d)Argon: 1s2 2s2 2p6 3s2 3p6\ne)Could be carbon, silicon, germanium, tin, or lead.  It's not specific enough.  And there is no such thing as an "elemen." Please treat chemistry with enough respect just type a "t" at the end of a word.  \nCarbon: 1s2 2s2 2p2\nSilicon: 1s2 2s2 2p6 3s2 3p2\nGermanium:  1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p2\nTin: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4d6 5s2 4d10 5p2 \nLead: \n1s2 2s2 2p6 3s2 3p6 4s2 3d10 4d6 5s2 4d10 5p6 6s2 4f14 5d10 6p2

Try drawing it yourself.  Here's the electrons per shell\n\n2.8.18.32.18.8.1 note they add up to 87, the Atomic Number for Fr.  Its Relative Atomic Mass is 223.\n\nWith this information you've got all you need.

mathematical dilemma. there is no answer to the question. Well at least none that are known. Just like the elements we know there out there but we have to figure them out first.  just like Einstein theory of fusion. its passable just not proved.

There are various means of determining this, and without any specific data on what elements are involved in the answer you are looking for, the link below is the best reference I can find that can answer this question in a mostly generalized way.

Yes.  Actually there is a mathmatical formula for finding the number of habital planets in the universe.  I remember that it is in three parts, but cannot for the life of me remember the exact formula.  It is based on number of stars (suns), how many planets would be orbiting the suns with the same life producing elements we have on earth, and the possibility of the same type of factors in evolution we had here on earth.  \nThe problem with the formula is that it represents only the type enviromental factors to produce "life" as we know it, not taking into regards other element based sources of life.  For instance, we are water based, whereas some other life forces may be silicon (Star Trek fans) based or based on an element we don't even know about.  \nYou may want to search the internet for the formula.  Sorry I can't remember it from my astronomy classes many years ago!

This is an answer I gave a few weeks ago. It helped me to get from failing Chemistry to University....maybe it will help you to understand the periodic table as well.\n\nMy Chemistry teacher taught me a great story which helped me learn the elements, which groups they were in, which periods, how many electrons they had etc and resulted in me going from a grade F to B. Every kid should learn this.\n\nHorrible Hairy Little Begger Boys Catch Newts On Friday Near Naples, Magnificent Albert Sits Planning Some Clever Arrangement Keeping Calm.\n\nOk, looks crazy until you break it down;\n\nH He Li Be B C N O F Ne Na, Mg Al Si P S CL Ar K Ca\n\nThen put it into the table\n\nH\nHe\nLi Be B C N O F Ne\nNa Mg Al Si P S Cl Ar \nK Ca\n\nYou will need to line them up because Yahoo has left align, but the trick is the story. \n\nThe groups 1-8 tell you how many electrons are in the outer shell, the periods tell you how many shells etc\n\nHope this helps!

Check out that link.  It has a picture that shows how it looks like: the grey Al atom is in the center, and 3 green Cl atoms are around it in a triangular arrangement.
