Question

first excitation potential of a hypothetical hydrogen like atom is 15 v. find the third excitation potential of atom​

Answer 1

The third potential is ( 75 / 4 ) eV

Explanation:

We are given that:

• First excitation potential = 15 V
• the energy of ground state=  - Eo

Given potential difference of hypothetical hydrogen is:

E2 - E1 = 15 eV

-Eo / 4 + Eo = 15

3 Eo / 4 = 15

c = 20 eV

Now for third excitation potential of hydrogen atom is:

E4 - E3 = - Eo / 16 + Eo = 75 / 4 eV

Thus the third potential is ( 75 / 4 ) eV.
