If Xenon is a noble gas how does it have such a high electronegativity of 2.60? It the only noble gas i know of that can form compound such as xenon
tetrafloride, how can this be?

Electronegativity of Xe is just a figure found by comparing the strength of a Xe-Xe and a F-F single bond to the strength of a Xe-F single bond. 2.6
isn't an especially high electronegativity, by the way.

Not high when compared to other elements, but high for a noble gas, which has full orbitals. My question is with full orbitals, how can xenon even
form molecules.

There is another thread where I posted some info about several noble gas compounds.
Electronegativity is an invented value. There are 4 different ways to calculate it which Pauli actually pulled out of his ass.
It can sometimes be useful, but electronegativity is often abused.
Pauli is an authority in the field of chemical bonding btw.
As electronegativity is purely calculated from bonding enthalpy, it doesn't take into account the high amount of energy that is necessary to initiate
the reaction.
