The ml quantum number can be equal to 0 is the correct statement about the quantum mechanical solution for the hydrogen atom.
- The lone electron in hydrogen can be found in an orbital in the ground state with the magnetic quantum number ml = 0, which is 1s.
- The same goes for this one electron, which can be excited to higher energy levels like 2p, 3p, and 3d, among others.
- Higher np sub-levels of the hydrogen atom's magnetic quantum numbers are -1, 0 and 1, respectively.
- The magnetic quantum numbers for the nd sub-levels are -2, -1, 0, 1, and 2. The information presented above shows that the magnetic quantum number for a hydrogen atom, ml, is not necessarily positive.
