Mercure (Hg, Z = 80)

80 Hg 200,592 u

Métal de transition Bloc d Groupe 12 Période 6 Liquide (CNTP)

Mercury is a chemical element with symbol Hg and atomic number 80. It is commonly known as quicksilver and was formerly named hydrargyrum (/haɪˈdrɑːrdʒərəm/). A heavy, silvery d-block element, mercury is the only metallic element that is liquid at standard conditions for temperature and pressure; the only other element that is liquid under these conditions is bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature.

Découvreur : unknown, before 2000 BCE
