subshell The number of subshells, or l, describes the shape of the orbital. It can also be used to determine the number of angular nodes. The magnetic quantum number, ml, describes the energy levels in a subshell, and ms refers to the spin on the electron, which can either be up or down. //chem.libretexts.org › Quantum_Numbers_for_Atoms See also what happens in an aphotic zone of a body of waterQuantum Numbers for Atoms – Chemistry LibreTexts

How many energy levels are there in an atom?
Every atom has an infinite number of energy levels available, depending on how much energy has been absorbed. In the ground state, there are seven (known/most-often-seen) energy levels which may contain electrons. The period number is the same as the highest energy level in that period at ground state.
