Electrons can\'t orbit at any old radius from the atom\'s nucleus, but are rathe

Question

Electrons can't orbit at any old radius from the atom's nucleus, but are rather restricted to only specific orbits at a fixed set of distances. This is called orbital quantization. Why this restriction? A For orbits that aren't quantized, electrons don't have enough energy to stay in orbit, and so fall into the nucleus OB. For electrons in orbit, an integer number of their quantum mechanical half-wavelengths need to fit into the orbit, otherwise they can't exist in that orbit For orbits that aren't quantized, electrons don't feel any electrical force to keep them confined to the orbit, so they leave the atom D. For electrons in orbit, an nge number of their whole quantum mechanical wavelengths need to fit into the orbit, otherwise they can't exist in that orbit

Explanation / Answer

This is because an integer number of the electron's quantum mechanical half wavelengths need to fit into the orbit, otherwise they can't exist in that orbit.

Hence option (b) is correct.
