In the electron configuration of aluminum, the 3p1 electron corresponds to the 3rd energy level (n=3) and is in the p subshell. The second quantum number, also known as the azimuthal quantum number (l), for a p subshell is 1. Therefore, the second quantum number of the 3p1 electron in aluminum is l = 1.

The principle quantum number of a hydrogen electron in its ground state is 1.
the quantum number n determines the energy of an electron in a hyrdogen atom.
Quantum numbers are values used to describe various characteristics of an electron in an atom, such as its energy, angular momentum, orientation in space, and spin. These numbers are used to define the allowed energy levels and possible configurations of electrons in an atom.
The first quantum number is the principal quantum number, denoted by "n." In aluminum, the 3p1 electron would have a principal quantum number of n = 3, since it is in the third energy level orbiting the nucleus.
n = 3
ms = +1/2
The principal quantum number n = 3 and the azimuthal or orbital angular momentum quantum number would be l =1 .l = 1

The first quantum number of a 2s electron in phosphorus is the principal quantum number, which specifies the energy level of the electron shell. For a 2s electron, the principal quantum number is 2.
n = 2
The first quantum number is the principal quantum number (n), which indicates the main energy level of an electron. For a 2s electron in phosphorus (atomic number 15), the first quantum number is 2.
