How many electron in an atom with atom...

How many electron in an atom with atomic number `105` can have `(n + l) = 8` ?

A

30

B

17

C

15

D

Unpredictable

Text Solution

Verified by Experts

The correct Answer is:
B
Write the configuration of 105 and find out electrons with n+l =8.
There are 14 electrons in 5f-orbitals `(5 + 3 = 8)` and 3 electrons in 6d-orbitals `(6+2 = 8)` making total = 17.
