`He^(+)` की आयनन ऊर्जा `19.6xx10^(-18)J" परमाणु"^(-1)` है | `Li^(+2)` की

A

`21.2xx10^(-18)J`/परमाणु

B

`44.10xx10^(-18)J//`परमाणु

C

`63.2xx10^(-18)J`/परमाणु

D

`84.2xx10^(-18)J`/परमाणु

Text Solution

Verified by Experts

The correct Answer is:
B
`Li^(+2)` के लिए `E_(1)=H` के लिए `E_(1)xxZ^(2)(Li)`
`He^(-)` के लिए `E_(1)=H` के लिए `E_(1)xxZ^(2)(He)`
इस प्रकार, `Li^(+2)` के लिए `E_(1)=(9)/(4)xx`(`He^(-)` के लिए `E_(1)`)
`=(9)/(4)xx19.6xx10^(-18)`
`=44.10xx10^(-18)J`/परमाणु
