Question

One d orbital can hold ___ electrons. A. 2 B. 6 C. 10 D. 14

Answer 1

Correct option is D)
Maximum number of electrons held in the d orbitals is 10.
There are 5 sub-levels in a d orbital, each one can have a maximum 2 electrons.
Hence, 5 sub-levels can have a maximum of 10 electrons.
Thus, s, p, d and f orbitals can accommodate a maximum of 2, 6, 10 an 14 electrons.

Answer 2

${ \red{ \tt{option \: (c)}}}$

Explanation:

One d orbital can hold 10 electrons.

The maximum number of electrons which can be hold by one d orbital is 10 electrons. It can hold less than 10 electrons in it's orbit but not more than 10 electrons. It's impossible to hold and never possible to hold more than 10 electrons in d orbital.
