Quantum numbers relate to electrons in that they denote the electrons angular momentum. Angular momentum is a vector, so it has a magnitude (1/2) and a direction (+ or -). Each orbital in an atom can only hold 2 electrons, and each electron will have a +1/2 spin and a -1/2 spin.

What is the first quantum number of a 2s electron in phosphorus?
The first quantum number, also known as the principal quantum number (n), indicates the energy level of an electron in an atom. For a 2s electron in phosphorus, which has an electron configuration of 1s² 2s² 2p⁶ 3s² 3p³, the principal quantum number is 2. This indicates that the electron is located in the second energy level.

What is the Principal Energy Level?
The principal energy level is the main energy level of an electron in an atom, designated by the quantum number "n." It indicates the approximate energy and distance of an electron from the nucleus. The higher the principal energy level, the higher the energy and distance of the electron from the nucleus.
Which of the quantum numbers is related to the size and energy of the orbital?
The principal quantum number (n) is related to the size and energy of the orbital. It indicates the main energy level of an electron and correlates with the average distance of the electron from the nucleus. A higher principal quantum number corresponds to a larger orbital size and higher energy.
