EXCITATION ENERGY AND EXCITATION POTENTIAL

Distinguish between Ionisation Potential and Excitation Potential.

What is excitation energy ?

If the I excitation potential of a hypothetical H-like is 162 V, then the value of II excitation energy is about :

The excitation energy of Lyman last line is

Define (i) Excitation energy (ii) Ionization energy

Assertion : An electron always absorbs or emits radiation of definite frequencies during excitation or de-excitation. Reason : The energy is quantised.
