Answer:
Mn Mn2+ + 2 e-
Since manganese is a transition metal, it is not possible to predict its ion charge from its group number. The charge on the ion is given by the roman numeral in its name. The charge is therefore +2
The symbol for the manganese(II) ion is therefore Mn2+ .
Mn has an atomic number of 25 , with 25 protons and 25 electrons in the neutral atom. In order for the ion to carry a charge of +2 it must have 2 more protons than it does electrons, so the atom must lose 2 electrons .
