Question

The minimum possible energy loss for an electron transition from ground state to next excited state in hydrogen atom is

• A. $1.02\text{eV}$
• B. $10.2\text{eV}$
• C. $13.6\text{eV}$
• D. $20.4\text{eV}$

Answer 1

The correct option is B $10.2\text{eV}$

The minimum possible energy loss for an electron transition from ground state to next excited state in a hydrogen atom is calculated by

$E_2-E_1=-3.4-(-13.6)=10.2\text{eV}$

This is the energy difference or loss between the first excited state and the ground state.
