So basically just look at the columns,

Anythin in the first 3 columns will have to lose 1, 2, or 3 electrons: column 1 will have an oxidation of +1, column 2 will have +2, and column 3 will have +3.

Columns 5,6,7: 5: elements in the 5th column will have an oxidation of -3, 6 column will have -2, 7 will have -1.

Column 4: you are either + or - 4, it doesn't really matter, it's hard for them to give up 4 electrons and it's hard for them to gain 4.

Column 8: they're already complete. They are the MOST reluctant to give up anything.

H: is in the first column, which means it has 1 electron/proton. We say it has an oxidation of +1 because if it lost that 1, it would be complete. We dont' say 7 because it's easier for it to lose 1 than gain 7 to be complete (elements close to "completion" are more reluctant to give up their electrons).

Cl: it's in the 7th column so it has an oxidation of -1. We say "-1" because it needs to GAIN one NEGATIVE electron (don't mistaken that as a "+1")!
