the number of proton=the number of electron= 12
Cl-1 has 17 protons and 18 electrons
Mg 2.8.2 likes to lose 2 electrons to become Mg 2.8, when it loses them it becomes an Mg 2+ ion.
A Mg atom has an equal number of protons and electrons, resulting in a neutral charge, while a Mg^2+ ion has lost two electrons, giving it a positive charge. This difference in electron configuration affects the reactivity and chemical properties of each.
There is no ion with the same number of electrons (= 11). Mg+ and Ne- do NOT exsist in normal chemistry. However Na+ and Mg2+ and Ne all have (equally) 10 electrons.
The Magnesium atom will lose 2 of its electrons to become a Magnesium ion with 10 electrons. (Mg2+) How many electrons does a magnesium ion have? How many electrons does a fluoride ion have? How many electrons does a fluoride ion have?

The atomic number of magnesium is 12. The cation loses two electrons for 10.

Absolutely not. Magnesium is magnesium, whether it's an ion or not. So it must have 12 protons. The number of electrons, however, is different. Neutral (non-ionic) magnesium has 12 electrons; the magnesium ion (Mg+2) has 10 electrons, which means it is isoelectronic with neon.
Sodium ions (Na⁺) and magnesium ions (Mg²⁺) are not isoelectronic. Isoelectronic species have the same number of electrons. Na⁺ has 10 electrons (11 protons minus 1 electron), while Mg²⁺ has 10 electrons (12 protons minus 2 electrons). Therefore, although both Na⁺ and Mg²⁺ have the same number of electrons, they differ in their nuclear charge, which affects their chemical behavior.

Magnesium is a group 2A element, and has 2 valence electrons. Thus, for it to become an ion (Mg^2+) is loses those 2 valence electrons.
Magnesium's atomic number is 12. Thus, neutral magnesium would have 12 electrons. Mg2+ therefore has 2 less electrons, or 10.
