The orbital quantum number is L=1
The spin quantum number is S=3
The total angular momentum quantum number is J=2
The state has a degeneracy of 5
It cannot be deduced how many electrons make up the state
How does the wave model of electrons orbiting the nucleus account for the fact that the electrons can have only discrete energy values?
Question options:
The wave model accounts for the types of orbitals an electron may occupy, not it's energy levels.
Electrons are only able to vibrate at particular frequencies.
The energy values of an electron only occur where its wave properties and probability clouds are mutually reinforcing.
When an electron wave is confined as standing wave, it is reinforced only at particular frequencies.
