For a 3s - orbital, value of `Phi` is given by following realation:
`Psi(3s)=(1)/(9sqrt(3))((1)/(a_(0)))^(3//2)(6-6sigma+sigma^(2))e^(-sigma//2)," where " sigma=(2r.Z)/(3a_(0))`
What is the maximum radial distance of node from nucleus?

A

Statement `(1)` alone is sufficient.

B

Statement `(2)` alone is sufficient

C

Both together is sufficient

D

Neither is sufficient

Text Solution

Verified by Experts

The correct Answer is:
B
`x rarr y + ._(2)^(4) H_(2)`
`y rarr O^(18) + ._(1)H^(1)`
`y = 9^(y^(19^(8)))`
`x=11^(X^(23))`
Hence `x=Na`
Na present in `3^(rd)` period
No of neutron `=23-11implies12`
mole of `Na = (4.6)/(23)implies 0.2`
Mole of neutron `implies 0.2 xx12 implies 2.4`
