2. Physical and Chemical Properties  Iodine is a nonmetallic, near to black solid.  The element has a relatively low melting temperature of 113.7  C.  Slowly sublimes to violet vapor (possibly harmful). Physical PropertiesChemical Properties

3. Background and History  Iodine was first discovered by French chemist Bernard Courtois in the year 1811.  It was isolated by Courtois in the same year.  The element was discovered in France.  The name “iodine” has its roots in Greek ioeides, meaning violet, or purple.

4. Everyday Use  Iodine is necessary for some animals, synthesizing thyroid hormones.  Iodine is also used for medical purposes, such as x- rays.  This is also used as radiation protection from any form of radiation.
