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 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 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 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 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 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.
