What is electronegativity?
It is a measure of how much a neutral atom wants an electron, metals have very low electronegativity, they almost always give electrons up, whereas non-metals usually uptake electrons, so they have a high electronegativity. It is formed from a sum of electron affinity and ionisation energy.
