Question
If elements principle quantum number n > 4 were no allowed in nature, the number of possible elements would be :
Options
A.60
B.32
C.4
D.64
Solution
No. electron that can accommodate in nth shell = 2m2
Total number of elements
= 2(1)2 + 2(2)2 + 2(3)2 + 2(4)2 = 60
Total number of elements
= 2(1)2 + 2(2)2 + 2(3)2 + 2(4)2 = 60
