I have two questions:

1. Which group in the periodic table reacts with H2 to form compounds with the general formula MH2?
A. Group 1A
B. Group 2A
C. Group 3A
D. Group 4A
E. Group 5A

2.Which reacts with F2 to form compounds with the general formula MF2?
A. Group 1A
B. Group 2A
C. Group 3A
D. Group 4A
E. Group 5A

I thought Bob Pursley answered this question about half way down the page. Here it is.
