Energy and angular momentum

Vedclass · Answer

(C) According to Bohr's theory of the atom,electrons can revolve only in those orbits in which their angular momentum is an integral multiple of $\frac{h}{2 \pi}$ (where $h$ is Planck's constant). Hence,angular momentum is quantized: $L = n \frac{h}{2 \pi}$.Also,the energy of an electron in the $n$-th orbit of a hydrogen atom is given by $E = -\frac{13.6}{n^2} \, 	ext{eV}$.Since $n$ can only take integer values $(n = 1, 2, 3, ...)$,the energy levels are also quantized. Therefore,both energy and angular momentum are quantized.

In Bohr's model of the hydrogen atom,which of the following pairs of quantities are quantized?
