Answers:Well actually, Matt C's suggestion is a periodic table, but it doesn't give oxidation numbers. Try this one instead. http://www.standnes.no/chemix/periodictable/oxidation-numbers-elements.htm
Answers:On top of the periodic table, you see IA, IIA, IIIA, IVA, that's the American old system of group number for representative elements. International system uses group 1, 2, 13, and 14. The I, II, III, IV, etc ... represents the valency (outermost electrons) of the elements in the group. So, Li, Na, Ka are with valency of 1; Mg, Ca are with valency of 2; Al, In are with valency of 3; C, Sn, Pb are with valency of 4. The group "B"s are transition metals, the valency is different.
Answers:I will give you a link to a periodic table that will help with "valencies" called oxidation states. Just click on the element and page down the window that comes up. The information will appear under the heading of oxidation states. Happy reading. :)
