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.

it should be p1 v1 = p2 v2

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
