When magnesium (mg) reacts with chlorine (cl) to form mgcl2, each atom of magnesium(gains, loses)(1,2,3,4) electron(s). as a result, each magnesium ion has a(1+,2+.3+,4+,1-,2-,3-.4-)charge.

2

they will get rid of 2 electrons

Explanation:

When magnesium (Mg) reacts with chlorine (Cl) to form MgCl2, each atom of magnesium(gains,loses)(1,2,3,4) electron(s) in a for all intents and purposes major way. As a result, each magnesium ion mostly has a(1+,2+.3+,4+,1-,2-,3-.4-)charge, demonstrating how when magnesium (Mg) reacts with chlorine (Cl) to form MgCl2, each atom of magnesium(gains,loses)(1,2,3,4) electron(s), which mostly is fairly significant.

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
