CBSE Class 11-science Answered
The amount of energy required to remove the electron from a Li2+ ion its ground state is how many times greater than the amount of energy needed to remove the electron from an H atom in its ground state is how much?. Please explain in detail.

Expert Answer
The energy of transition is given by E = -13.6 Z2 eV (1/nf2 – 1/ni2). Since both n values for the transition in question are the same, the ratio of the energies determined only by the ratio of the Z2 or (1)2/(3)2 or 1/9. Thus the energy required to remove an electron from Li2+ is 9 times greater than hydrogen.
