Question 450: Atoms & Nuclei

Question

If the ionisation energy for the hydrogen atom is 13.6 eV , then the energy required to excite it from the ground state to the next higher state is nearly

Accepted Answer

Minimum energy required to excite from ground state,
$$\mathrm{E}_{\min }=13.6\left[\frac{1}{1^2}-\frac{1}{2^2}\right]=10.2 \mathrm{~eV}$$

Answer

10.2 eV

Answer

13.6 eV

Answer

$-$10.2 eV

Answer
