Question 15 When moving oxidation numbers down as subscripts in an ionic bond, do you include the charge (+/-)? A)Yes
B) Depends on the element
C)No
D)Depends on how large the compound is Previous

C)No

Explanation:

When moving oxidation numbers down as subscripts in an ionic bond, you do not include the charge either positive or negative.

The process of moving oxidation number down as subscript is known as exchange of valency.

The combining power is used in exchanging valency and this is oxidation number exchanged. The number corresponds to the number of electrons usually lost or gained or shared by atoms of elements during chemical combination or the number of positive or negative charges carried by ions.

The combining power is exchanged as simple whole number ratio during the formation of chemical formulae of compounds.

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).
