The uncertainty inherent to quantum mechanics has long left physicists wondering whether the observations we make on the ...

Magnetic Quantum Number (ml): Determines the orientation of the orbital in space. For a given l, ml can range from - l to + l, including 0. This means there are 2 l + 1 orbitals with the same shape ...

In the context of the 2s subshell, this means that one electron can have the quantum numbers n = 2, l = 0, ml = 0, and ms = +1/2, while the other electron in the same 2s orbital must have n = 2, l = 0 ...
