Answer:

${\bf{\huge{Hola !!}}}$

1. All the listed elements belong to 3rd Period of the periodic table.

2. B and F will form an Inorganic Compound. As both the elements are divalent, an atom of X combines with an atom of Y to form a compound with the formula XY. The nature of the bond in the compound is ionic, since the element X is a metal as it is from group 2. The element Y is a non-metal as it is from group 16.

3. Elements A and B are more likely to be metals .

5. Valency of C = 3

Valency of G = 1
