Web12 apr. 2024 · The ionization energy is a measure of the capability of an element to enter into chemical reactions requiring ion formation or donation of electrons. It is also … Web(a) Energy of ground state of He+ = −13.6× n 2z 2=13.6×2 2 = −54.4 eV (iv) We know that, Total energy=Kinetic energy+Potential energy P.E.=2T.E and K.E.=−T.E For example- In the Bohr ground state the potential energy is -27.2 eV. The kinetic energy is +13.6eV, so when we add the two together we get the total energy to be -13.6eV.
