What is the maximum number of elements...

What is the maximum number of elements if the electrons above `n = 4` do not exist in nature ?

A

40

B

40

C

44

D

100

Text Solution

Verified by Experts

Since `n = 1,2,3, and 4`
`(1s)/(2),(2s 2p)/(8),(3s 3p 3d)/(18) ,(4s 4p 4d 4f)/(32)`
Thus total number of existent element is `2+8+18+32 = 60`
