nuclear charge f-1how many electrons in a ground state argon atom have a magnetic quantum number (ml) equal to -2? a. 12
b. 10
c. 8
d. 6

Respuesta :

no of electrons in the ground state= 8

Finding the number of electrons?

Argon: atomic number= 18

     number of electrons = 18.

Ar(18)= 1s² 2s² 2p² 3s² 3p⁶

Value of m= -2

m belongs to (-l,l) where l = azimuthal quantum number

m∈(-2,2)

so the total number of electrons for m= -2 is 8
