The number of element present in the fifth period is

A

`18`

B

`32`

C

`8`

D

`24`

Text Solution

Verified by Experts

The correct Answer is:

A

The fifth period involes the filling up of the following subshells: `5s, 4d`and `5p`. Thus, the number of elemets in the fifth period is `2+6+10 = 18`.
