Answer 1

Al^3+;Al

Step-by-step explanation:

When a metal ion is formed, the corresponding ion is smaller than the atom from which it was formed.

Oftentimes, the formation of a metal ion leads to the loss of an entire shell. The reduces the ionic radius compared to the atomic radius. Hence the metal ion is always much smaller than the metal atom.
