^{-1}

) for a

\text{Be}^{3+}

ion in its ground state. \newline (Given:

N_A=6.02\times10^{23}\,\text{mol}^{-1}

1\,\text{eV}=1.60\times10^{-19}\,\text{J}

.) (a)

5.2\times10^{6}\,\text{J mol}^{-1}

(b)

2.1\times10^{8}\,\text{J mol}^{-1}

(c)

2.1\times10^{7}\,\text{J mol}^{-1}

(d)

3.3\times10^{5}\,\text{J mol}^{-1}
