Question

how many D electrons can have spin Quantum numbers minus half​

Answer 1

Answer:

5

Explanation:

because d orbit has 5 d orbitals and in each orbital one electron will have minus half spin quantum number.So as 5 orbitals 5 minus electrons will have minus half spin quantum number

Answer 2

Answer:

At a maximum of 5 electrons can have a negative spin individually or in other words they have a quantum number of minus half.

Explaination:

This is because, d block has 5 orientations in it. Maximum of 2 electrons can be accommodated in a single orientation.

(one with +1/2 and another with -1/2)

so, there will be 1 electron in each orientation with -1/2. Totally, 5 electrons will be there in d block with -1/2.
