Key Differences
Betadine is a widely recognized brand name for a povidone-iodine antiseptic solution. Iodine, on the other hand, is a chemical element with the symbol "I" and atomic number 53, found naturally in certain foods and also available in dietary supplements.
Betadine's primary component is iodine, but it's not pure iodine. It combines iodine with a carrier molecule called povidone, which allows the iodine to be released slowly, providing prolonged antiseptic action. Iodine in its pure form can be a strong oxidizing agent and can be caustic to the skin.
The use of Betadine in medical settings is often as a topical disinfectant before and after surgery or for minor wound care. Iodine can be used for similar purposes, but due to its strength, it's more commonly diluted or combined with other agents, like in Betadine, to reduce potential irritation.
Beyond its antiseptic properties, iodine is essential for human health. It plays a crucial role in thyroid function and the production of thyroid hormones. Betadine, while containing iodine, is not intended for ingestion and doesn't serve as a dietary source of iodine.
Both Betadine and iodine have a brownish color, making them easily recognizable when applied to the skin. The presence of iodine gives Betadine its characteristic color. However, while Betadine is primarily for external use, iodine has both external and internal applications, depending on its form and concentration.

Iodine
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.
Betadine
(pharmaceutical drug) Povidone-iodine, used as a topical antiseptic.
Iodine
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.
