A cation.
well The electrons on that shell have nowhere to go so they jump off and become ionised
It becomes a cation
The nonmetals usually gain or share however many electrons they need to complete their outer shell. Metals tend to lose the electrons in their outer shell, so that one of the inner shells essentially becomes the outer shell.
it becomes a positive ionit becomes a positive ion
It becomes a positive ion. However, energetically it is more favorable for magnesium to lose two electrons. It still becomes a positively charged cation.
when a neutral atom loses an electron it becomes a positive ion. it now has a stable outer most shell.
It becomes positive.
When a sodium atom loses an electron in its outer shell, it forms a positively charged sodium ion (Na+). This process happens in order to achieve a stable electron configuration similar to that of a noble gas, which typically have a full outer shell of electrons.
When boron becomes an ion, it typically loses three electrons to achieve a full outer shell, resulting in a charge of +3.

You can determine how many electrons are gained or lost by looking at the atom's charge. If the atom gains electrons, it becomes negatively charged; if it loses electrons, it becomes positively charged. The difference between the atom's original and final charge tells you how many electrons were gained or lost.

Calcium typically loses 2 electrons to form a stable ion with a 2+ charge. This is because calcium has 2 electrons in its outer shell, and it is energetically favorable for it to lose these electrons to achieve a full outer shell configuration.
The nonmetals usually gain or share however many electrons they need to complete their outer shell. Metals tend to lose the electrons in their outer shell, so that one of the inner shells essentially becomes the outer shell.
