Aluminum has valence electrons. the easiest way for al to acquire a full outer shell is to __ __ electrons, forming an ion with a charge

This element has 3 valance electrons and it will loose electrons to form a ion.

Explanation:

Aluminium is the 13th element in our periodic table.

The valance shell electronic configuration of this element is:

As, there are 3 electrons in the outermost shell, Therefore, total number of valence electrons of this element are 3.

For this element loosing 3 electrons will be easy than to gain 5 electrons to acquire a full outer most shell configuration. Therefore, this element will loose 3 electrons.

When this element looses 3 electrons, it looses negative charge and starts to form positive ion. And it form an ion having +3 charge.
