Answer:

magnesium is a 2A group metal and one of the characteristics of this group is that it has 2valence electrons, magnesium is a metal and a metal gives electrons to another element when creating a compound

since magnesium gives 2electrons the number of electrons and protons is in disbalance

Mg Z=12

e-=p+

p+=Z

p+=12

e-=12

Mg2+

Z=12

p+=12

e-=12-2

e-=10

so there would be 2 more protons than electrons since protons have a positive charge that is presented as 2+
