Answer 1

Answer #1

Answer) In the periodic table metaliic character increases as we move fromtop to bottom and decreases as we move from left to right.

The decrease in the metallic character from left to right in periodic table is due to increase in force of attraction between nucleus and electron as size of the atom decrease across period and hence it cant lose the valence electron easily.

The metallic character follows the order:

Zn > Ge > Se

So, Se is least metallic.
