How are electronegativity and metallic & non-metallic characters related?

Explanation

`rarr` Greater the electronegativity values of an element indicates that non metallic nature and low metallic nature of that element.
`rarr` Lower the electronegatiity value of an element indicates that low non metallic nature and high metallic nature of that element
Electronegativity `prop` Non metallic nature
Electronegativity `prop (1)/("Metallic Nature")`
