Magnesium is in group 2 of the periodic table.
A magnesium atom will lose 2 electrons to form a stable 2+ ion.
is in group 7 of the
A chlorine atom will gain 1 electron to form a stable 1- ion.
In this example the electrons are shown as dots and crosses.
Two chlorine atoms will
each gain one
the magnesium atom. The atoms become ions.
The attraction between the oppositely charged
forms the ionic bond between magnesium and chlorine.
