Salesite vs. Iodine — What's the Difference?

(mineral) An orthorhombic-dipyramidal mineral containing copper, hydrogen, iodine, and oxygen.

Iodine is a chemical element with the symbol I and atomic number 53. The heaviest of the stable halogens, it exists as a semi-lustrous, non-metallic solid at standard conditions that melts to form a deep violet liquid at 114 degrees Celsius, and boils to a violet gas at 184 degrees Celsius.

Symbol I A lustrous, purple-black, corrosive, poisonous halogen occurring as a diatomic molecule, I2, that easily sublimes to give a purple gas and is a trace element essential for proper thyroid function. Radioactive isotopes, especially I-131, are used as medical tracers and in thyroid disease diagnosis and therapy. Iodine compounds are used as germicides, antiseptics, and dyes. Atomic number 53; atomic weight 126.9045; melting point 113.7°C; boiling point 184.4°C; density of gas 11.27 grams per liter; specific gravity (solid, at 20°C) 4.93; valence 1, 3, 5, 7. See Periodic Table.

An antiseptic preparation containing iodine in solution, used to treat wounds.

A chemical element (symbol: I) with an atomic number of 53; one of the halogens.

An antiseptic incorporating the element.

An iodide.

(transitive) to treat with iodine.

A nonmetallic element, of the halogen group of atomic number 53, occurring always in combination, as in the iodides. When isolated it is in the form of dark gray metallic scales, resembling plumbago, soft but brittle, and emitting a chlorinelike odor. Symbol I. Atomic weight 126.90. If heated, iodine volatilizes in beautiful violet vapors.

A nonmetallic element belonging to the halogens; used especially in medicine and photography and in dyes; occurs naturally only in combination in small quantities (as in sea water or rocks)

A tincture consisting of a solution of iodine in ethyl alcohol; applied topically to wounds as an antiseptic
