Discovered in 1825-1826

Chemists Antoine Jerome (from Germany) and Carl Jacob Lowig discovered it separately

Carl Lowig’s Chemist professor realized bromine was unknown and asked Lowig to make more

That took long enough for Antoine Jerome (from France) to do a report on this new element. Jerome is usually credited with the discovery of bromine

Symbol, atomic number, and mass of BROMINE!

Cost to purchase: Bulk- $0.15 per 100g,

Pure- $5 per 100g

Bromine is a NATURAL element!Pictures of BROMINE

Physical Properties of Bromine:

• Liquid

• Reddish-brown

• Mobile and heavy

• MP: -7.2˚C

• BP: 58.8˚C

• Density: 3.1 g/cm-3 at 20˚C

Chemical Properties of Bromine:

• Not flammable

• Bromine atoms are “less reactive radicals of bromine”

• Corrosive

A bit of bromine; you can see its reddish vapor!

Bromine is not as common as 3/4 of the chemical elements on Earth’s crust

Bromine, in liquid and vapor forms!

Where is Bromine Found?

Bromine is found in oceans in

China

Israel

The U.S.

PROCESS TO EXTRACT

Chlorine is added to sea water that has sodium bromide/ potassium bromide

Since chlorine is more reactive than bromine, it replaces bromine in the chemical reaction:

Cl2+2NaBr 2NaCL + Br2

USES OF BROMINE…

PhotographyFlame Retardant

Pesticide

Gasoline Additive

Medicine

Fun Facts Bromine is a dangerous element- contact with skin

creates severe burns

Vapor of bromine irritates throat, nose, and eyes

Not a pleasant smell

Only non-metal element that is a liquid under “normal” conditions
