Neutrons: 14
Protons: 13
Electrons: 10

Explanation:

Typically in any standard atom, we have the same number of electrons as protons.

But we have a 3+ ion here.
Therefore we have 3 less electrons than we normally have.
13-3 = 10

Therefore there are 10 electrons present.

The electronic configuration will be:

#1s^2 , 2s^2, 2p^6 #

Remember the last 3 electrons are donated elsewhere to make that 3+ aluminium ion.
