If tin it’s +4, then S2 is (-2 x2)

4+-4= 0

Why is it -2 is this because it's in group 6? We weren't taught the rules for group 6. We were only told about group 7. The rule for group 7 is 1- when a metal? Is it true when it's a metal in group 7 it's 1 - or does it mean non-metal?

Also would the rule for group 7 be it's 2- if it is bonded to a metal or non-metal?

Do you mind telling me all the rules for oxidation numbers as my teacher seems to have missed out some content. Thanks!
