According to Bohr's theory of hydrogen atoms, the product of the binding energy of the electron in the $n$ th orbit and its radius in the $n$ th orbit

Options:

Answer:

Solution:

$E_{n} \propto \frac{1}{n ^{2}}, r_{n} \propto n^{2}$

Hence $E_{n} r_{n}$ is independent of $n$ .

$E_{1} r_{1} = (13.6 eV) (0.53 \overset{˚}{A})$

$E_{n} r_{n} ≃ 7.2 eV \overset{˚}{A}$
