The fourth quantum number, known as the spin quantum number (denoted as ( m_s )), can take on values of +1/2 or -1/2. For the 3p³ configuration, which has three electrons in the p subshell, the spin quantum numbers of the electrons can be either all +1/2 or a combination of +1/2 and -1/2. However, in many cases, the three electrons will have two with spin +1/2 and one with spin -1/2, reflecting the Pauli exclusion principle and maximizing total spin. Thus, the fourth quantum number for one of the electrons in 3p³ can be either +1/2 or -1/2, depending on its specific spin orientation.
The electron configuration for the element with atomic number 15 (phosphorus) is 1s2 2s2 2p6 3s2 3p3.
The electron configuration of an element with atomic number 15 (phosphorus) is 1s2 2s2 2p6 3s2 3p3. This means it has 2 electrons in the first shell, 8 in the second shell, and 5 in the third shell.

The fourth quantum number, known as the electron spin quantum number, can have a value of +1/2 or -1/2 for an electron in an orbital.
ms = -1/2
l=1

The second quantum number (angular momentum quantum number) for a 3p electron is 1. This indicates the electron is in the p subshell, which has angular momentum quantum number values of -1, 0, 1.
ms = -1/2

The third quantum number of a 2s electron in phosphorus is 0, because the 2s orbital has zero angular momentum. The quantum number indicates the orientation of the orbital in space.
The second quantum number, also known as the azimuthal quantum number (l), for a 3p orbital is 1. This indicates that the orbital has a p shape, which is characterized by l=1.
m(I)=0 (apex)
The third quantum number for a 2p3 electron in phosphorus is the magnetic quantum number (m). It specifies the orientation of the orbital in space and can have values ranging from -l to +l, where l is the azimuthal quantum number for the orbital. So, for the 2p orbital with l=1, the possible values of m are -1, 0, and 1.
