Dihydrogen monoxide parody oxygen atom. Literally, the term "dihydrogen monoxide" means "two hydrogen, one oxygen", consistent with its molecular formula: the prefix "" in "dihydrogen" means "two", the prefix "" in "monoxide" means "one", and an oxide is an oxygen atom attached to another atom in an ionic compound. Using chemical nomenclature, various names for water are in common use within the scientific community. Some such names include "hydrogen oxide", as well as an alkali name of "hydrogen hydroxide", and several acid names such as "hydric acid", "hydroxic acid", "hydroxyl acid", and "hydroxilic acid". The term "hydroxyl acid" used in the original text
Thallium(III) oxide Thallium(III) oxide Thallium(III) oxide, also known as thallic oxide, is a chemical compound of thallium and oxygen. It occurs in nature as the rare mineral avicennite. Its structure is related to that of MnO which has a bixbyite like structure. TlO is metallic with high conductivity and is a degenerate n-type semiconductor which may have potential use in solar cells. A method of producing TlO by MOCVD is known. Any practical use of thallium(III) oxide will always have to take account of thallium's poisonous nature. Contact with moisture and acids may form poisonous thallium compounds. It is produced by the
