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