Detailed explanation-1: -Magnesium atom attains stable electronic configuration of nearest noble gas-Neon by losing two electrons from its valence shell and becomes positively charged magnesium ion.

Detailed explanation-2: -Magnesium loses an electron when forming with Oxygen because it takes less energy for the element to loose 1 electron then to gain 7. it also becomes stable once the electron transfer to oxygen making a complete outer shell and having 8 valence electron which follows the octet rule.

Detailed explanation-3: -The most common and stable type of magnesium atom found in nature has 12 protons, 12 neutrons, and 12 electrons (which have a negative charge). Atoms of the same element with different neutron counts are known as isotopes.

Detailed explanation-4: -Mg loses 2 electrons to form Mg+2 ion with 10 electron. This ion has an electronic configuration with complete outermost octet. This is the reason for the stability of magnesium ion.
