In phosphorus (atomic number 15), the electron configuration is 1s² 2s² 2p⁶ 3s² 3p³. For the 3p³ electrons, the second quantum number (l) for the p subshell is 1. Thus, the second quantum number for a 3p³ electron in phosphorus is 1, indicating that it is in a p orbital.
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 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, 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.
Phosphorus in is 3rd period. So it has 3 electron shells.
