Orbitals and Energy Levels

Postby Diana A 2L » Sun Oct 20, 2019 11:58 pm

Are orbitals different from energy levels? The relationship between the two is unclear to me. Are there orbitals within different energy levels? Is whether an electron is located in a certain energy level unrelated to what orbital it is in, or is there a connection between the two?

within the energy level, the volume of space is called the orbital.

If it helps, you can think of the various quantum numbers for electrons as a hierarchy of sorts. Starting from the bottom going up, the spin quantum number () represents the spin of a given electron. The magnetic quantum number () represents the specific orbital that contains that electron. Each of these orbitals can hold a maximum of two electrons that must have differing spins. The angular momentum quantum number represents the shape of the orbital where the electron can be found and is also referred to as the subshell (e.g. s orbitals have l=0 and are spherical). Lastly, the principal quantum number (n) represents the energy level of your subshell.

Tl;dr: At most two electrons of differing spins can fit in each orbital. Each subshell contains one or more orbitals. Each energy level contains one or more subshells.
