Why does mercury have a low melting point?
The reason mercury has such a low melting and boiling point is because the structure of it’s valence electron shell doesn’t easily form crystal structures.
Why is mercury a good conductor of electricity?
Mercury is a metal because is has free electrons as do all metals. As a result it is a good conductor of electricity as are all metals. All metals form compounds by giving up those free electrons to become positive ions. Mercury gives up two electrons to become an ion of charge plus two. Most metals f
Why do metals have higher melting points than nonmetals?
Metals tend to have higher melting and boiling points than non-metals; this is because of metallic bonding; where nuclei float in a sea of electrons in crystalline latices. The atoms are all very compact, and it takes a lot of energy to force these atoms into a liquid or gas. Compare this to non-metals like Oxygen, which can only bond with 1 or 2 other Oxygen atoms at a time. (When pure oxygen, obviously there are molecules with more than 3 oxygen atoms.)
Which element is liquid at room temperature?

Overview
Chemistry
All known mercury compounds exhibit one of two positive oxidation states: I and II. Experiments have failed to unequivocally demonstrate any higher oxidation states: both the claimed 1976 electrosynthesis of an unstable Hg(III) species and 2007 cryogenic isolation of HgF4 have disputed interpretations and remain difficult (if not impossible) to reproduce.
Unlike its lighter neighbors, cadmium and zinc, mercury usually forms simple stable compound…

Etymology
"Hg" is the modern chemical symbol for mercury. It is an abbreviation of hydrargyrum, a romanized form of the ancient Greek name for mercury, ὑδράργυρος (hydrargyros). Hydrargyros is a Greek compound word meaning "water-silver", from ὑδρ- (hydr-), the root of ὕδωρ (hydor) "water", and ἄργυρος (argyros) "silver". Like the English name quicksilver ("living-silver"), this name was due to mercury's liquid and shiny properties.
History
Mercury was found in Egyptian tombs that date from 1500 BC.
In China and Tibet, mercury use was thought to prolong life, heal fractures, and maintain generally good health, although it is now known that exposure to mercury vapor leads to serious adverse health effects. The first emperor of a unified China, Qín Shǐ Huáng Dì—allegedly buried in a tomb that contained rivers of flowing mercury on a model of the land he ruled, representative of the riv…
