1st excitation potential for the H-like ...

1st excitation potential for the H-like (hypothetical) sample is 24 V. Then:

A

Ionisation energy of the sample is `36 eV`

B

Ionosation energy of the sample is `32 eV`

C

Binding energy of `3^(rd)` excited state is `2 eV`

D

`2^(nd)` excitation potential of the sample is `(32xx8)/(9) V`

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
`1st` excitation potential `=10.2 Z^(2)=24 V :. Z^(2)=24//10.2`
`:. IE=13.6 Z^(2)=(13.6xx24)/(10.2)=32 eV`
Binding energy of `3^(rd)` excited state `=0.85 Z^(2)=(0.85xx24)/(10.2)=2eV`
`2^(nd)` excitation potential of sample `=12.09 Z^(2)=(12.09xx24)/(10.2)=(32xx8)/(9) V`.
