I enjoyed this start to finish, very fascinating. See ya on the next one. Paz.

I have a question. So my understanding is that the high electrical conductivity of metals is due to the "freeness" of electrons in metallic bonding. If gold keeps its outer electrons so tightly bound to the nucleus, why is it such a good electrical conductor?

This is really interesting. So Gold hangs onto it's electrons more tightly because of the high number of protons in the nucleus? Does this mean that other metals with high numbers of protons are also soft?

How does this affect other elements? Is this why mercury is a liquid?

It's more the case with mercury which is not solid at all at room temperature.
