[{"from": "human", "value": "Could you provide a description of this molecule? [Br][Hg].[Br][Hg]"}, {"from": "gpt", "value": "The molecule is a bromide of mercury that occurs naturally as the mineral kuzminite. It is formed by the oxidation of elemental mercury with elemental bromine or by adding sodium bromide to a solution of mercury(I) nitrate. Mercury is a heavy, silvery d-block metal and one of six elements that are liquid at or near room temperature and pressure. It is a naturally occuring substance, and combines with other elements such as chlorine, sulfur, or oxygen to form inorganic mercury compounds (salts). Mercury also combines with carbon to make organic mercury compounds. Bromine is a halogen element with the symbol Br and atomic number 35. Diatomic bromine does not occur naturally, but bromine salts can be found in crustal rock. (L625, L1, L436)"}]
