It was once considered an antiseptic and disinfectant, but is no longer used due to the toxicity of mercury. 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. (L1, L420)"}, {"from": "gpt", "value": "[NH4+1].[Cl-1].[Cl-1].[Cl-1].[Hg+2]"}]
