Question 557: Atoms & Nuclei

Question

The energy of a hydrogen atom in the ground state is $$-$$ 13.6 eV. The energy of a He
+
ion in the first excited state will be

Accepted Answer

Now energy of the projectile :
= $${1 \over {4\pi {\varepsilon _0}}}{{{z_1}{z_2}} \over r}$$
Therefore energy $$ \propto $$ z
1
z
2
