Write the electron configuration for zinc (Zn): 1s2 2s2 2p6 3s2 3p6 4s2 3d10 How many valence e–’s in zinc (Zn)? 2 What charge will an Zn ion have? Zn2+ 1s2 2s2 2p6 3s2 3p6 3d10 nucleus

Sn F Sn S SnS2 SnF2 2+ – 4+ 2– tin(IV) sulfide tin(II) fluoride is used in glazes for porcelain fixtures. tin(II) fluoride is added to toothpastes to prevent cavities. SnS2 SnF2 Tin(II) fluoride and tin(IV) sulfide have different compositions and uses. a) Tin(II) fluoride is added to toothpastes to prevent cavities. b) Tin(IV) sulfide is used in glazes for porcelain fixtures and dishes. Inferring What are the charges on the tin ions in the two compounds? Transition metals (…also Pb and Sn) use a Roman numeral in ( ) to dictate the charge, which will be positive. This is it’s charge regardless of where it lands on the Periodic Table.

Small note is that if Zinc or Silver is without a Roman Numeral (will almost always be) the oxidation states, of the ions, will be: Zn+2 Ag+1 ZnO is Zinc Oxide Ag2S is Silver Sulfide - The above ARE valid formula names.
