Ionisation poetential is the poetential calculate from the orbit n=1 to the n = infinity and that is given as:
E = > 13.6 × z²
z²= 20/13.6............(1)
Excitaion energy is given as :
=> -13.6 × (z² / 4 – z² / 1)
from equation . (1) we get,
=> -13.6 × (5/13.6 – 20/13.6)
=> 15 V
E = > 13.6 × z²
z²= 20/13.6............(1)
