Chapter 11, Problem 89CE

Interpretation Introduction

Interpretation:

The first ionization energy of lithium is given. The energy required to convert $25g$ of lithium atoms to lithium ions is to be calculated.

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,

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

The moles of an atom can be calculated using the given formula.

$\text{Moles}\text{of}\text{an}\text{atom}\left(\text{mol}\right)\text{=}\frac{\text{Given}\text{mass}\left(\text{g}\right)}{\text{Gram}\text{atomic}\text{mass}\left(\text{g/mol}\right)}$
