Question

An electron has azimuthal quantum number is 2. Its magnetic quantum number is​

Answer 1

Answer:

-2, -1, 0, 1, 2

Explanation:

m=2l+1=2×2+1=5

There are 5 magnetic quantum numbers.

l=2

m ranges from -l to l

Thus, m can be

-2, -1, 0, 1, 2

Answer 2

12th/Chemistry

Structure of atom

Answer :

◈ Azimuthal quantum number 'l' is also known as orbital angular momentum or subsidiary quantum number which defines the three dimensional shape of the orbital$.$

◈ Magnetic orbital quantum number 'm' gives information about the spatial orientation of the orbital with respect to standard set of co-ordinate axis. For any sub-shell (defined by 'l' value) 2l + 1 values of m are possible and these values are from -l and +l.

ATQ,

Azimuthal quantum no. of eˉ = 2

Magnetic quantum number :

• m = 2l + 1
• m = 2(2) + 1
• m = 5 (total number)

Values (-l to +l) : -2, -1, 0, +1, +2
