please someone give me a hand at this problem. . .

Describe the Bohr model of the atom. What is Bohr’s key idea (involving matter waves) that makes the Bohr atom have discrete
energy levels?

1. It think that the question is flawed, as it confuses the idea of matter waves with the Bohr model of the atom.

Bohr postulated that angular momentum is quantized in order to explain the discrete energy levels of atoms, see here:

The idea of matter waves came later. It was proposed by de Broglie, see here:
