Iodine

A few dozen pellets of Iodine in an ampoule. The inside is also covered with countless tiny flecks of Iodine.

The Halogen group: roughly 30% |f| gas, |cl| gas, |br| liquid and vapor, and |i| pellets, all in ampoules

An old Iodine sample embedded into an acrylic cube. It created an interesting pattern of discoloration inside it.

The Halogen group: |f| (probably only 33% F, 67% |he|), |cl|, |br|, and |i|

In most cases, |cl|, |br|, and |i| are the only Elements in the halogen group that people can get. |f| is overwhelmingly reactive and requires special equipment to contain, while |at| is overwhelmingly radioactive and has not been isolated in a sample large enough to see.

Pure Iodine is a dark purple, almost black solid in average Earth temperatures. This macro photo shows mostly pure Iodine beads inside of a glass ampoule, which has been turned horizontally. The texture of the beads look extremely similar to blueberries, but don’t be fooled, pure Iodine can be toxic and cause chemical burns.
