They are very unlikely to bond with any element, whether it is metallic or not.

Explanation: -

Group 18 elements have 8 electrons in their outermost shell or valence shell.

As such they have already fulfilled their octet. Due to this they are stable. They do not tend to react and bond with any element, whether it is metallic or not.

This is why group 18 elements are called noble gases.
