The magnetic quantum range or ml describes the orientation in area of a specific orbital. It is SP2 hybridisation for Argon and the no. of electrons are 2.
The feasible values of ml may be decided in view that it is able to handiest be an integer withinside the range l±1. If ml is 0 then the price of l can handiest be same to 0. If the price of the azimuthal quantum range is 0, this corresponds to the s orbital.
Thus, you handiest want to matter the electrons which might be withinside the s orbitals of the argon atom. The electron configuration of Argon is given below. There are 6 electrons which have ml=0 in view that there are 6 electrons in s orbitals (1s, 2s and 3s)
Ar:1s22s22p63s23p6.
