The quantum number that describes the direction of electron spin is the spin quantum number, denoted as ( s ) or ( m_s ). It can take on one of two values: +1/2 or -1/2, indicating the two possible orientations of an electron's intrinsic angular momentum. This quantum number is crucial for understanding the behavior of electrons in atoms and their arrangement in orbitals.
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.
The second quantum number, also known as the azimuthal quantum number (l), describes the shape of the electron's orbital. For a 3p electron, the value of l is 1, corresponding to the p subshell. Therefore, the second quantum number of the 3p1 electron in aluminum is 1.
The third quantum number, known as the magnetic quantum number (m_l), describes the orientation of the orbital in which the electron resides. For the 2s orbital, which is spherical, the magnetic quantum number can only be 0. Therefore, for the 2s¹ electron in aluminum, the third quantum number (m_l) is 0.
The second quantum number, also known as the azimuthal quantum number (l), describes the shape of an electron's orbital. For the 2s orbital, l equals 0, indicating a spherical shape. Therefore, the second quantum number of the 2s² electron in phosphorus is 0.
The third quantum number, also known as the magnetic quantum number (m_l), describes the orientation of the orbital. For a 3s electron, which is in the s subshell, the possible values of m_l are 0 (since s orbitals have a spherical symmetry). Therefore, the third quantum number for a 3s² electron in phosphorus is m_l = 0.

The spin quantum number of an electron describes the intrinsic angular momentum of the electron, which is a fundamental property of particles like electrons that is not related to their orbital motion. It is quantized in units of ħ/2, where ħ is the reduced Planck constant, and can have values of either +1/2 or -1/2.

The magnetic quantum number indicates the orientation of an electron's magnetic moment in a magnetic field. It helps determine the direction in which the electron will align itself within the field.
