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
