It has a negative charge; to be more specific it has a charge of -3, since it has only 5 valence electrons and it would like to gain 3 more to be stable at 8.
Formal charge is used when creating the Lewis structure of a molecule, to determine the charge of a covalent bond. Formal charge is the difference between the valence electrons, unbound valence electrons, and half the shared electrons.
Metals as found in the Periodic Table have no "extra" electrons. They are electrically neutral because they have the same amounts of protons and electrons or + and - charges respectively. However metals react with non-metals to form Ions, cations to be more precise, in this case they actually lose electrons resulting in a positive charge. In other words, metals never have "extra" electrons, they either have a neutral charge or they are lacking electrons and have a negative charge.
The most likely charge for an ion of magnesium (Mg) is 2+. This is because magnesium has two valence electrons, and it is energetically favorable for it to lose these electrons and achieve a stable octet configuration, resulting in a +2 charge.

Phosphorus forms P3- ion and it has 8 valence electrons (5 valence electrons from phosphorus and three from the charge).
It has a negative charge; to be more specific it has a charge of -3, since it has only 5 valence electrons and it would like to gain 3 more to be stable at 8.
Yes, calcium has valence electrons - two, in fact (it is a divalent chemical element).
Most probably 10 electrons as a phosphide ion with 3-charge has 8 valence electrons.
An atom's charge changes when it gains or loses electrons. Atoms naturally tend to lose or gain electrons to level out at eight valence electrons (valence electrons are electrons in the outermost energy level), so the only atoms that keep their charge are ions with eight valence electrons or the Noble Gases, atoms on the far right of the periodic table that have eigth valence electrons and a nuetral charge.

The halogens, group 17, have 7 valence electrons. When they form ions, they gain 1 more valence electron and become ions with a charge of 1-.
The phosphorus -3 ion. The phosphorus -3 ion gains 3 electrons and acts like argon.
