Answer 2

H<0
S>0

Answer 3

You're right. The element is found in group VIA, and the element could be S, Se, or Te. It is a common misconception to assume that nonmetals only have negative oxidation numbers. Generally, metals only have positive oxidation numbers, but nonmetals, with only a few exceptions (i.e. F) have both positive and negative oxidation numbers. If your element is combined with an element which is more electronegative, then your element will have a positive oxidation number. It your element is the more electronegative then it will have the negative oxidation number. Be careful of the words "transition" and metalloid". The transition metals, like all metals have only positive oxidation numbers. Having positive and negative oxidation numbers is not a trait of just the metalloids.

Answer 4

negative
