Identify which sets of quantum numbers are valid for an electron. each set is ordered (n,ℓ,mℓ,ms).

Which set of three quantum numbers does not specify an orbital in the hydrogen atom?

Quantum numbers arise naturally from the mathematics used to describe the possible states of an electron in an atom. the four quantum numbers, the principal quantum number (𝑛), the angular momentum quantum number (𝓁), the magnetic quantum number (𝑚_𝓁), and the spin quantum number (𝑚_s) have strict rules which govern the possible values. identify all allowable combinations of quantum numbers for an electron.

What rule/principle states that electrons fill orbitals from lowest energy to highest energy?
