Question

(a) Find the first excitation potential of $H{e}^{+}$ ion.

(b) Find the ionization potential of $L{i}^{++}$ ion.

Answer 1

(a) First excitation Potential of

$H{e}^{+}=10.2\times Z^2$

= $10.2\times 4=40.8V$

(b) Ionization Potential $L{i}^{++}$

= $13.6V\times Z^2$

= $13.6\times 9=122.4V$
