Answer 1

Answer:

Na(11)

Answer 2

Atomic size

Explanation:

As you move down an element group in the periodic table, the atomic radius increases. So the atomic size increases as we move from up to down of a group. So Sodium (Na) has a bigger atom size when compared to Chlorine  (Cl) which is above it on the periodic table.

As you move down an element group in the periodic table, the atomic radius increases. So the atomic size increases as we move from up to down of a group. So Chlorine (Cl) has a bigger atom size when compared to Flourine (Fl) which is above it on the periodic table.
