Bromium vs. Bromine — What's the Difference?

Bromium was a venture capital–backed startup based in Cupertino, California that worked with virtualization technology. Bromium focused on virtual hardware claiming to reduce or eliminate endpoint computer threats like viruses, malware, and adware.

Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour.

A dense, volatile, corrosive, reddish-brown, nonmetallic liquid halogen element that exists as a diatomic molecule, Br2 having a highly irritating vapor. Chiefly isolated from brines, it is used in producing fumigants, dyes, water purification compounds, and photographic chemicals. Atomic weight 79.904; atomic number 35; melting point -7.2°C; boiling point 58.8°C; density of gas 7.59 grams per liter; specific gravity (liquid, at 20°C) 3.12; valence 1, 3, 5, 7. See Periodic Table.

(uncountable) A nonmetallic chemical element (symbol Br) with an atomic number of 35; one of the halogens, it is a fuming red-brown liquid at room temperature.

(countable) A bromine atom

One of the halogen elements, related in its chemical qualities to chlorine and iodine. Atomic weight 79.8. Symbol Br. It is a deep reddish brown liquid of a very disagreeable odor, emitting a brownish vapor at the ordinary temperature. In combination it is found in minute quantities in sea water, and in many saline springs. It occurs also in the mineral bromyrite.

A nonmetallic largely pentavalent heavy volatile corrosive dark brown liquid element belonging to the halogens; found in sea water
