For Mg to attain a pseud noble gas formation it must lose two electrons, becoming the ion Mg2+.
To attain the noble gas configuration, Ca would have to lose 2 electrons, Mg would have to lose 2 electrons, Ba would have to lose 2 electrons, and Be would have to lose 2 electrons.
Selenium should gain two electrons and lose six electrons to achieve a noble gas electron configuration.
the atomic no of oxygen is 8 to reach the nearest noble gas electronic configuration it excepts 2 electrons and becomes isoelectronic to Neon.
Electrons are both gained and lost. Electrons are both gained and lost.

Electrons are the ones gained or lost in a chemical reaction. Electrons are gained in oxidation and lost through the chemical reaction known as reduction.
It gains two to look like Ar.
An atom that has gained an electron becomes a negatively charged ion.
