The second quantum number, or "l" which describes the subshell (s, p, d, f, etc).
Azimuthal quantum number
The quantum number that indicactes the shape of an orbital in called the angular momentum quantum number.
Azimuthal quantum number
34 azimuthal quantum number
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 angular momentum number shows the shape of the electron cloud or the orbital. The magnetic quantum number, on the other hand, determines the number of orbitals and their orientation within a subshell.
represents the spin of the electron.
n is the first quantum number. It is the principle quantum number. It refers to what energy level it is and will be one greater than the number of nodes in the orbital. l is the second quantum number. It is the angular momentum quantum number and refers to the shape of the orbital. ml is the third quantum number. It is the magnetic quantum number and it refers to the orientation of the orbital. ms is the fourth quantum number. It is the spin quantum number and refers to the magnetic character of the orbital.
l=0
l=0
The angular momentum quantum number, symbolized by l, indicates the shape of an orbital.
The principal quantum number n = 3 and the azimuthal or orbital angular momentum quantum number would be l =1 .l = 1
