How does the size of an aluminum atom change when it becomes an ion with a charge of 3 plus?

The outermost (3rd) shell of aluminium is occupied with 3 electrons will gave away 3 electron away as it forms an ion, hence the outermost shell which was occupied by those 3 electrons gone, thus the size of aluminium atom decrease.
Added:
Above that there are 13 proton charges (3 extra) to attract more the remaining 10 electrons, so they'll stay closer to the nucleus.
Hence all positively charged ions are smaller than their respective neutral atoms.
The reversed is true for negative ions: Chloride (Cl-) is bigger compared to Chlorine.

What is aluminum overall charge of an atom?
The neutral atom hasn't a charge.
What occurred to give aluminum a 3 charge?
For an aluminium atom to gain a 3+ charge, it must lose its 3 outermost electrons; its valence electron. It then becomes an aluminium cation.
An atom that gives up electrons becomes an?
This atom become a cation (positive charge).
What is it called when a atom that has gained or lost and electron and now has a net electric charge?
When atoms (elements) gain or loose electrons, they become Ions. If an atom looses electrons it becomes +1 charge, whereas if an atom gains electrons it becomes -1 charge.
When an atom loses an electron the atom becomes an ion is?
Its charge lose an negative charge. So it is positively charged. +1

What would happen if a proton was added to a aluminum atom?
If a proton were added to an atom of aluminum, the atom would become a silicon ion with a single positive charge.
What Happens When An Atom Becomes Iron With A 2 Charge?
it becomes happy!
What happens when atom looses electron?
If an atom loosed electrons then it becomes an ion. The electrical charge in the atom becomes a positive ion.
If an atom loses an electron 'negative charge' it becomes?
If it loses an electron (negative charge) it becomes positive.
What will be the charge when a phosphorus atom becomes an ion?
Most commonly, it will have a 3- charge.
When an atom becomes a ion with a 2- charge the atom?
an ion with a 2- charge has 2 more electrons than usual
When an atom becomes an ion with a negative 2 charge the atom?
Gained 2 electrons
An atom that gives up electrons becomes an?
This atom become a cation (positive charge).
What happens when an atom loses an electron from its outer most shell?
well The electrons on that shell have nowhere to go so they jump off and become ionised
What happens to an atom when it takes on a negative charge?
An atom takes on a negative charge by gaining electon/electrons and thus, becomes an anoin
