BROMINEBY JAMES BERRY
Br35
BROMINE
79.90
Atomic Mass:The number of protons
and electrons in a Bromine
atom
Element Symbol:
The abbreviated
form of BromineElement Name:
The name Bromine
Element State of Matter:
The state of Bromine at room
temperature (liquid)
Atomic Mass: The number of protons plus
the number of neutrons in a Bromine atom (45 neutrons, 35 electrons, 35 protons)
ISOTOPES
Different isotopes of an element vary in the amount of neutrons in the nucleus. However, they are still the same element, because they have the same number of protons. The different numbers represent that particular
isotope’s atomic mass.COMMON BROMINE ISOTOPES

COMPOUNDSCompounds are when one element is
chemically combined with another element. These are some more common Bromine
compounds that are combined with one or more other elements.
C H Br is a compound that was used in unleaded gasoline to prevent leaded compounds within the engine
of the vehicle.

AgBr is a compound that is used in film for photography. It is the largest usage of Bromine today.
The Discovery of Bromine
Antoine Balard was born September 3rd, 1802 and died March 30th, 1876. A French Chemist, Balard was 21 when he was studying plant life in a salt
marsh. When he was studying the water, he noticed what would later become Bromine. Bromine is still
extracted from sea water today.
Bromine Atom
To find out how many protons and electrons there are, you
simply look at the atomic number,
which in Bromine’s case is
35.
To find out the number of
Neutrons, you take the atomic
mass, 79.90, and round it to the nearest whole number, 80. Because the
atomic mass is the number of
neutrons plus the number protons, you subtract the atomic mass by the number of
protons, and you get 45.
Bromine Information
HARMFUL
Bromine is either found in natural brine deposits, or extracted from seawater. There are many Bromine deposits because you
can extract it from salt water. The estimated oceanic abundance is 6.73 x 101, which is a lot considering how much seawater there is. Bromine does not harmfully affect the environment, however,
when it touches bare skin, it causes painful sores.
Bromine InformationBromine Family: The Halogens,
Number 17
Like few other elements, Bromine is a Non-Metal, which means it has opposite properties of metal
elements.
Bromine PropertiesFreezing Point: -7.2° CBoiling Point: 58.78° CDensity: 3.11 g/cm3
Color: red brownLiquid at room temperature
Bad SmellSoluble in water and alcohol
Bromine Uses
Bromine is used in making fumigants, flame-proofing agents, water purification compounds,
dyes, medicines, sanitizers, and inorganic bromides for photography. Bromine salts are also used in hot
tubs because of the higher temperatures.Bromine costs $5.00 per 100 grams
Bromine Interesting Facts
Bromine is one of the only two liquids on the
periodic table, along with Mercury, and the
only liquid non-metal.
Bromine is poisonous and burns
skin on contact.
Bromine smells very bad and actually
comes from the Greek word bromos,
which means stench.Bromine can actually be found in a purple dye found in a sea mussel called the murex.
