The nonmetals in Groups 6A and 7A ____.
a. lose electrons when they form ions
b. have a numerical charge that is found by subtracting 8 from the group number
c. all have ions with a –1 charge
d. end in -ate
Check my thinking but I don't think the correct answer is listed. I suspect the answer is supposed to be (b); however, all of the metals in the free state have a zero charge. I think the question is flawed.

b. have a numerical charge that is found by subtracting 8 from the group number
Yeah, ima say the answer would be B.
Answer: Option (A) is the correct answer.
Explanation:
A non-metal is a substance which tends to gain electrons from another atom in order to acquire noble gas electronic configuration.
For example, elements of group 6A have 6 valence electrons and elements of group 7A have 7 valence electrons.
Hence, in order to know the charge acquired by the elements of these groups we should subtract their group number from 8.
So, elements of group 6A forms (8 - 6) = 2. That is ion is formed in general.
Similarly, elements of group 7A forms (8 - 7) = 1. That is ion is formed in general.
Thus, we can conclude that the ions formed by non-metals in group 6A and 7A have a numerical charge that is found by subtracting the group number from 8.
