The ionisation energy of `A(g)` is similar to in terms of magnitude `-`

Options

A. electron affinity of `A^(+)(g)`
B. electron affinity of `A(g)`
C. ionisation energy of `A^(+)(g)`
D. ionisation energy of `A^(2+)(g)`

Answer

1

Explanation

`A^(+)+erarrA(g)+EA` It is reverse of `I.E.` of A
`|I.E.|=|EA|`
