if values of quantum number can be c...

if values of quantum number can be considered as follow : n=1,2,3,…….. `oo`
l=- to (n+1)
m=- l to +l (interfral values incleuding zero )
`s=(1)/(2) ,+(1)/(2)`
According to above consideration the maximum number of electrons associataed with 3rd shell is :

A

50

B

32

C

40

D

60

Text Solution

Verified by Experts

The correct Answer is:
a

n=3, l=0,1,2,3,4,
No. of values for l=0`to `1
l=1`to ` 3
` l=2 to 5`
l=3to 5
l=3tio 7
l=4 to 9 `
`therefore "total " e^(-) = 25 xx2 = 50`
