The third quantum number, known as the magnetic quantum number (m_l), describes the orientation of the orbital. For a 3s electron, the principal quantum number (n) is 3, and the azimuthal quantum number (l) for an s orbital is 0. Therefore, the magnetic quantum number for a 3s electron is m_l = 0.
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.
Phosphorus has 5 valence electron. It forms anion by gaining 3 electrons.
Phosphorus in is 3rd period. So it has 3 electron shells.
The first quantum number, also known as the principal quantum number (n), indicates the main energy level of an electron in an atom. For the 3p¹ electron in aluminum, the value of n is 3, as it is in the third energy level. Therefore, the first quantum number for the 3p¹ electron is 3.

The quantum numbers for phosphorus are n = 3, l = 1, ml = -1, 0, 1, and ms = -1/2. The principal quantum number (n) indicates the energy level, the azimuthal quantum number (l) indicates the subshell and shape of the orbital, the magnetic quantum number (ml) indicates the orientation of the orbital, and the spin quantum number (ms) indicates the spin of the electron.
Phosphorus has 5 valence electron. It forms anion by gaining 3 electrons.
The electron configuration of phosphorus is [Ne]3s2.3p3.
Phosphorus in is 3rd period. So it has 3 electron shells.
Phosphorus, like all atoms, tries to achieve a full electron shell. For Phosphorus to achieve its full shell and obtain an electron configuration that is isoelectronic with Argon, it must gain 3 electrons. Therefore, Phosphorus forms a -3 anion.
An atom with a principal quantum number of 3 has 2 radial nodes in its electron cloud.
