If `x,y` and z are electronegativity, ionisation potential and electron`-`affinity respectively. Then the electron affinity `(z)` in the terms of electronegativity `(x)` and ionisation potential `(y)` will be `:`

Options

A. `x=(y+z)/(2)`
B. `z=(x-y)/(2)`
C. `z=(x^(2)-y^(2))/(2)`
D. `z=2x+y`

Answer

1

Explanation

`x=(y+z)//2` according to Mulliken's.
