We make use of quantum numbers in physics and chemistry because physical quantities such as energy, charge, and angular momentum are quantized (have discrete values). this allows us to construct probability clouds of electrons in atoms. true false

True

Explanation:

The energies, angular momentum, charge of an electron in the atom is quantized which means that it is an integral multiple of some value.

For example, the angular momentum is quantized which is equal to the integral multiple of h/ 2π, which means that if the electron is 1 orbit , the angular momentum is h/ 2π , if the electron is in second orbit, the angular momentum is 2h/ 2π.

Thus, similarly energy is also quantized according to Bohr's theory which means that we can calculate the energy of the electron in various stated and thus we can also calculate the probability of that electron in the given state.

Hence, the given statement is correct.
