Ionisation enthalpy of Na would be same as

A

electron affinity of `Na^(+)`

B

electronegativity of `Na^(+)`

C

electron affinity of `He`

D

ionization potential of Mg

Text Solution

Verified by Experts

The correct Answer is:
A
`NararrNa^(+)+e^(-)," IE of Na "=+ve`
`Na^(+)+e^(-)rarr " E.A. of "Na^(+)=-ve`
Both are equal but opposite in nature
