Given $$KE$$ $$=$$ $$1312$$ $$KJ/moleIt$$ means T.E $$=$$ $$-$$ $$1312KJ/moleE2$$ of $$He+=-Z2n2E1$$                $$=-2222E1(1312)$$                 $$=$$ $$-1312$$ $$KJ/moleKE$$ of electron in $$2nd$$ orbit of $$He+$$ $$=$$ $$+1312$$ $$KJ/mole$$                 $$=-3232(1312)$$                 $$=$$ $$-1312$$ $$KJ/moleKE$$ of electron in $$3rd$$ orbit of $$Li+2$$ $$=$$ $$+1312$$ $$KJ/mole$$
