Low value of electrode potential(Mn3+/Mn2+) for scandium shows Sc3+ is stable while comparitively low value of electrode potential(Mn3+/Mn2+) for vanadium shows Vn2+is stable.Why?
The energy of the electron in the first orbit of He + is -871.6x 10 -20 J . The energy of the electron in the first orbit of hydrogen would be : (1) -871.6 x10 -20 J
