Question

What is the value of m for dz2

Answer 1

0 is m value.
and it is 100% sure.

Answer 2

Answer:

The value of m for $d_{z^2}$ is zero.

Concept:

Magnetic Quantum Number: The solution of azimuthal wave equation gives us a constant m, which is called magnetic quantum number.

Magnetic quantum number has 2l + 1 values where l is orbital quantum number.

The values of l for specific orbitals are given below -

Orbital                                Value of l

    s                                           0

    p                                           1

    d                                           2

    f                                            3 and so on

Explanation:

m here denotes the magnetic quantum number.

$d_{z^2}$ denotes the subshell of d orbital.

We are given a subshell of d orbital.

For d orbital, l = 2

∴ m will have 2(2) + 1 values, i.e., 5 values.

m = -2, -1, 0, +1, +2  and these value specify 5 subshells in d orbital namely, $d_{xy},\ d_{yz}, \ d_{z^2}, \ d_{zx}, \ and \ d_{x^2 - y^2}$.

The values of magnetic quantum number for different subshells are given below -

$d_{xy} = -2\\d_{yz} = -1\\d_{z^2} = 0\\d_{zx} = +1\\d_{x^2-y^2} = +2$

Hence, The value of m for $d_{z^2}$  = 0.
