Chapter 8, Problem 8A.4P

Interpretation Introduction

Interpretation:

The ionization energy of ${\text{Li}}^{2+}$ has to be predicted when the ionization energy of ${\text{He}}^{+}$ is $54.36\text{eV}$.

Concept introduction:

The energy required to remove an electron from an ion or isolated atom is known as its ionization energy.  The ionization energy of metals is generally lower than the ionization energy of nonmetals.  The formula of ionization energy for an atom is given by the expression shown below.

  $I=\frac{Z^2{m}_e{e}^4}{8{\epsilon }_0^2{n}^2{h}^2}$
