Chapter 11, Problem 3RQ

Interpretation Introduction

Interpretation:

Beryllium has much higher third ionization energy than its second ionization energy Explanation has to be given for this difference.

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 first then it will be first ionization energy, if the removed electron is second then it will be second ionization energy.

For example,

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