This is for skeptics who think they can recognize bogus theories. Is this believable or does it look like the kind of gobbledeegoop seen on bogus audiophile websites?
Why is Mercury a liquid at room temperature?
I found a way to explain why mercury is a liquid and gold, which has a similar electronic structure and is next to mercury on the periodic table is a solid. I explain this with both quantum mechanics and Einstein's theory of relativity.
The average radial velocity for a 1s electron in an atom heavier than hydrogen is approximately
(Z/137)c
where:
Z = atomic number
c = speed of light
For mercury (80/137)c = 0.58c or 58% of the speed of light. Plugging this value into the Lorentz mass transformation equation gives mrel = 1.23mrest
mrel = mass at velocity v
mrest = mass at rest
From Dirac quantum mechanics we know that s1/2 and p1/2 contract quite a lot, but p3/2 to a much lesser extent. This in turn induces an exension outward of d and f orbitals relative to a and p orbitals. Spin orbit coupling (relativistic splitting) becomes large for heavier elements.
To explain why mercury is a liquid its known that the relativistically contracted 6s orbital is filled and therefore the two 6s electrons do not contribute much to the metal-metal bonds. This is the opposite with gold. One must conclude that the bonding is brought about largely by van der Waals forces and probably also through weak 6p orbital interaction. This is why the Hg-Hg bond is so weak and therefore why mercury is a liquid at room temperature.
