Question

For the hydrogen atom, the energy of the electron is defined by the factor En=13.58/n2eV. Here n is positive integer. The minimum quantity of energy which it can absorb in its primitive stage is:
  1. 1.00eV
  2. 3.39eV
  3. 10.19eV
  4. 6.79eV

A
3.39eV
B
1.00eV
C
6.79eV
D
10.19eV
Solution
Verified by Toppr

En=13.58n2

In primitive stage at n=1,E1=13.58eV

Minimum energy in excited stage,

n=2,E2=3.395eV

Energy absorbed =3.395+13.58=10.19eV

Hence, the correct option is D
