Answer 2

Answer:

The correct answer is Be.

Explanation:

All the given elements are from II-A group. In general, moving from top to bottom in a group the ionic character increases and covalent character decreases. Be is at the top in the group having the highest covalent character. Be forms covalent compounds with Cl, Br and I. Be has 2 valence electrons. Due to its small size, it has high polarizing power & forms a covalent bond.

Hence, the correct answer is Be.
