Solution
The correct option is A 10
correct answer: option 'A'
The principal quantum number is 3, that means the 3rd shell.
Azimuthal quantum number is 2, that means d orbital.
This is because,
0 → s - orbital
1 → p - orbital
2 → d - orbital and so on
So, we have to find number of electrons present in 3d orbital.
The principal quantum number doesn't affect the number of electrons present in an orbital. So, ultimately, the number of electrons present in 3d = number of electrons present in d orbital = 10Thus, the 3d orbital contains 10 electrons
