Question

The minimum energy required to excite a hydrogen atom from its ground state is ____________.

Options

• 13.6 eV

• - 13.6 eV

• 3.4 eV

• 10.2 eV

Answer 1

The minimum energy required to excite a hydrogen atom from its ground state is 10.2 eV.

Explanation:

Minimum energy required to excite from ground state

`= 13.6 [1/1^2 - 1/2^2]`

` = 10.2  "eV"`
