Question

the total number of values of m,for p, sub shell​

Answer 1

Answer:

For l = 1 (p-type orbitals), m can have values of –1, 0, +1, so we find three 4p orbitals. For l = 2 (d-type orbitals), ml can have values of –2, –1, 0, +1, +2, so we have five 4d orbitals.

Answer 2

Answer:

17

Explanation:

The magnetic quantum number specifies the orientation in space of an orbital of given energy and shape. This number divides the subshell into individual orbitals which hold the electrons; there are (2L+1) orbitals in each subshell. Thus, the s subshell has only one orbital, the p subshell has three orbitals, and so on.

For n=4, we have s,p,d,f subshells.

For s subshell, we have 2×0+1=1.

For p subshell, we have 2×1+1=3.

For d subshell, we have 2×2+1=5.

For f subshell, we have 2×3+1=7.

The total value of m will be 1+3+5+7=16

Hence, the correct option is C
