In chemical compound ability of an atom ...

In chemical compound ability of an atom to attract shared electron toward itself is called electronegativity. Various scales are given to measure electronegativity like Pauling scale, Mulliken scale, Allred-Rochow's scale. Electronegatigity of an element also depends on various parameters.
If electron of an element is `6eV` and ionisation energy is `16.4eV` then electronegativity element on Pauling scale is:

A

`2.5`

B

`3.5`

C

`4.0`

D

`3.0`
