Difference in electron gas pressure and molecular gas pressure?

Question

What is the significance that the electron gas pressure for silver is very much larger than the typical value of molecular gas pressure?

Answer 1

Give us some numbers, then.

Addendum:

I've just done a crude back-of-the-envelope calculation (literally!) using the simple kinetic theory equation for the pressure of an ideal gas.  At room temperature the electron gas pressure came out at about 3*10^9 Pa.  Compare this with sea level air pressure at normal temperatures of about 10^5 Pa.  Wow, some 30,000 times bigger! Don't know what the significance of this is, though.
