Answer 1

Mg

HOPE IT HELPS............

Answer 2

Answer:

Mg ...Magnesium.

Explanation:

Because , Mg is in the 2nd group . In group, atomic radius goes on increasing. It is in the 3rd period . In group atomic radius goes on decreasing. Atomic radius of Mg is larger than another elements. So, Mg is larger atom. It's atomic radius is larger , because it has 2 electron in last outermost orbit, it loses those electron to become stable . It's nucleus apply less force of attraction so radius increases. Mg is after the Be in group 2. Boron and Silicon are on the right side so decrease atomic radius.

This will help you...I hope that..
