Why is gold so Electronegative?

What is less known is that the contraction of the 6s orbital makes gold have the highest electronegativity among all metals and enhances its trend to present a negative oxidation state.

Why is gold called inactive metal?

Since the 6s orbital with one electron is contracted, this electron is more tightly bound to the nucleus and less available for bonding with other atoms. The 4f and 5d orbitals expand, but can’t be involved in bond formation since they are completely filled. This is why gold is relatively unreactive.
