What are the three main parts to an electrons “address” used in the current atomic theory that describe an electrons location?

Hope this helps

Explanation:

These are called quantum numbers: there are 4, but the first three are mainly used, only in orbital notation will you use all four.

The first is the electron's energy level or "shell", used as n. (Principle QN)

The second relates to the shape of the orbital and is used as l, when n and l are put together it defines the sublevel or subshell. (Angular Momentum QN)

The third one relates to the orientation of the electrons in that sublevel used as m(sub)l. (Magnetic QN)

The fourth one relates to the spin states of the electron, since they spin opposite directions, used as m(sub)s. (Electron Spin QN)
