3. 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.

4. COMPOUNDS
Compounds 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 2 H4 Br 2 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.
5. 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.
6. Bromine Atom
To find out the
number of
Neutrons, you take
the atomic mass,
To find out how 79.90, and round it
many protons and to the nearest whole
electrons there are, number, 80. Because
you simply look at the atomic mass is
the atomic number, the number of
which in Bromine’s neutrons plus the
case is 35. number protons,
you subtract the
atomic mass by the
number of protons,
and you get 45.
7. Bromine Information
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.

8. Bromine Information
Bromine Family: The Halogens, Number
17
Like few other elements, Bromine is a Non-Metal, which
means it has opposite properties of metal elements.
9. Bromine Properties
Freezing Point: -7.2° C
Boiling Point: 58.78° C
Density: 3.11 g/cm3
Color: red brown
Liquid at room temperature
Bad Smell
Soluble in water and alcohol
10. 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
