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 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.
