Can u tell me the charges of each element in the periodic table from group 14-15
Carbon,Silicon,Germanium,Tin,Lead
Nitrogen,Phosphorus,Arsenic,Antimony,Bismuth
Thanks....also do you know any good chemistry websites?

Well, the charges are not definate... but I can give you some answers on some of the charges of each of your elements. - Carbon has too many charges to list, Silicon does as well, Germanium is usually a +4 charge, Tin is either (II) or (IV) which are +2 or +4, "L" is not an element shorthand, but I know you meant Lead (Pb). Pb can be +2 or +4 in the stages of (II) and (IV). Usually, Nitrogen is a -3 charge, Phosphorus is a -3, Arsenic is usually a -3, Antimony (Sb, not An, but once again, I know what you meant) is usually +3 or +5. There are a ton of good chemistry sites, it all depends on what sort of chemistry needs you require.

Your elements are not from groups with fixed charges. The charge will depend on the electronegativity of other species in the compound. Just remember that every atom reacts to get a filled valence shell. With 4 valence electrons (half-filled shell), carbon can either donate or withdraw electron density with equal ease. Pair it with hydrogen and it hogs the electrons. Pair it with oxygen and the opposite is true.(Remember that non-metals bond covalently and share electron density even if unevenly rather than transferring electrons as metals do to non-metals). Nitrogen is 5 over or 3 short of a filled valence shell so in NH3, it draws electron density to the tune of 3 and in NO3- it gives to the tune of 5. Going down the groups, you will see the same trends because it's all about getting those valence shells filled, and there are equal numbers of valence electrons as you go down each group.

Im confused. Elements do not have charges by definition. An element has an equal number of electrons and protons thus creating zero net charge. Maybe you should look at isotopes or ions for net charges.

is a good resource for all elements on the periodic table.
Follow the links to find a wealth of information on any element.
