Structure of a metal in gas phase

I'm going to use aluminium in my example, but this is applicable to all metals.

Aluminium has delocalised electrons. It has aluminium cation -electron attraction. It's easier to visualize the atomic structure of aluminium in solid form.

But if it's in the gas phase, will delocalised electrons return to the atom itself, or is there going to be an electron and cation mixture (electrons floating around)?

So can aluminium (or any other metal) conduct electricity as a vapour, and what would its conductance be compared to its solid form?
