periodic table listing the charges
i need a free periodic table that lists the "charges" that each element generally has
example:
Oxygen generally has a charge of -2
Helium is a noble gas and is very stable to it has a charge of zero
chlorines charges in order of most common to least common are -1, +1, +3, +5, +7
a list of these would be great- and a list of compounds and their charges would be wonderful also :D
im in chemistry currently and im having trouble making chemical equations so ive gotten desperate and put this up :oops:
plz help :?

Did you have did this?

wonderful information, I had
wonderful information, I had come to know about your blog from my friend nandu , hyderabad,i have read atleast 7 posts of yours by now, and let me tell you, your website gives the best and the most interesting information. This is just the kind of information that i had been looking for, i'm already your rss reader now and i would regularly watch out for the new posts, once again hats off to you! Thanks a ton once again, Regards, periodic table with charges
This site has many versions of the Period Chart to chose from; the NY Regents' Table has oxidation states in it; there are others. Try this website for downloadable tables.

[color=darkgreen]Please be careful not to confuse [b]charges[/b] with [b]oxidation states[/b]. Charges of simple ions are as follows:
Hydrogen: either +1 or -1, depending on whether it's hydrogen or hydride.
Column 1A metals (Li, Na, K, Rb, Cs, Fr): +1.
Column 2A metals (Be, Mg, Ca, Sr, Ba, Ra): +2
Column 3A (Al, Ga): +3
Column 4A (C, Si): usually form covalent compounds or are found in polyatomic ions.
Column 5A (N, P, As): -3
Column 6A (O, S, Se, Te, Po): -2
Column 7A (F, Cl, Br, I, At): -1.
These are the charges. Many times, the charges are one of the common oxidation states. Transition metals (the ones in the d-block, ie, iron, cobalt, chromium, nickel, etc.) are often capable of having different charges, for example iron can be ferric or ferrous.[/color]
