Chapter 11, Problem 57AE

Interpretation Introduction

Interpretation:

The trend in ionization energies has to be examined, provided if the first ionization energy of potassium is lower than that of the first ionization energy of calcium but the case is reverse for second ionization energies.

Concept Introduction:

Ionization energy:

  The amount of energy required to remove an electron from the atom is known ionization energy.  If the removed electron is outermost valence electron then it will be first ionization energy, if the removed electron is second then it will be second ionization energy.

For example,

  $\text{Na}\text{+}\text{Ionization}\text{energy}\stackrel{}{\to }{\text{Na}}^{\text{+}}\text{+}\text{e}$
