If a wire is at +120V does it have more electrons or fewer
than a wire of equal size at ground?

The very premise of your question is flawed hence there is no direct answer.

assuming no external electrostatic fields.

If they aaare exactly thhe same size (or better the exact same wire)
the wire with +120V will have a few fewer electrons.

120V is not much of a static charge and the deficiency of electrons
will be relatively small.

Actually to correct you all, a +120v bias to any conductor has no mor
electrons than the grounded wire at all, no matter what the gauge
Voltage potential means nothing interms of the amount of electrons i
a conductor, because iof they are both copper, the electron count i
the same regardless of charge either way

Not to be snotty, but the facts present themselves....This is
popular trick question in electron physics...

For the rest of you, a static charge can develop at as little a
0.001pV, and as a whole the assumption of "static
electricity is wholly misunderstood. Run your fingers through you
hair and you can generate 50V easily.....You should stud
"peeling" a bit more when it comes to stati
charge...lifting a sheet of plastic off a table can generate as muc
as 1500V..
