or you can give me a web to go to
thanks!!!

Carbon is used for the arbitory units in avagadros number.. this means that the number of particles in one mole of carbon is this much and the rest of the elements follow this rule aswell (1.062X10^23) this is also shown as NA..
Helium is in the noble gas group this means that its outer shell is completley full this means that it has a valency of 0. It is only has one shell. so it is a very boring element.. often only found as a gas.. there are several different isotopes of helium this means that they have the same number of electrons and protons but a different number of neutrons which only changes the mass of the atom.. there are three isotope H3 H2 H1
Hydrogen can be tested for by filling a testube full of it in its gas form and placing a lighted splint this will cause a small explosion or pop! it has 1 electron in its outershell and it happens to only have one electron..
Copper and zinc are both semi metals or transistion metal. their valency (what they can bond with) varies.
Copper burns green! in flame tests Zinc burns blue..
Both produce precipitates when placed in acid...
Check out wikipedia im studying A level chemistry and physics and biology science really is interesting if you can get your head round it! if wikipedias a bit heavy look out for power point presentations that hang about all over the web.. take my email id love to help with any furthur probs!!!

What kind of facts?...There is so much data to sift through...looking at the periodic table will give you at least a dozen facts right off the bat for each.

You can check the periodic table of elements. It will tell you the atomic number, mass, the number of valance electrons, and shells

Carbon is the lead in pencils, aka, graphite.
Hydrogen is in the sun.
Helium is in some balloons.
Iron is something.
Copper is in pennies.
Nickel is in the Earth.
Zinc is something.
