[O][=Hg]"}, {"from": "gpt", "value": "The molecule is an oxide of mercury that occurs naturally as the mineral montroydite. It is often used in the production of mercury and as a material for cathodes for mercury batteries. 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, L427)"}]
