Sulfur Element

1

Sulfur Element

• Tasteless
• Odorless
• Light yellow
• Nonmetallic element
• Flammable
• Also called brimstone
• Mentioned in the Bible
• Essential in combustion

• Has been known since prehistoric times
• Insoluble in water
• Most stable variety is rhombic sulfur yellow
  crystalline solid

Uses for Sulfur

• Used in the vulcanisation of natural rubber, as a
  fungicide, and as a fumigant
• Used in batteries
• (battery acid)
  

• Most important manufactured chemical in the world
  
• Compounds are used in the bleaching of dried
  fruits and for paper products

Sulfurs History

• From the Sanskrit word "sulvere" meaning
  "sulfur" also from the Latin word "sulphurium"
  meaning "sulfur
• Possibly Antoine Lavoisier should be credited
  with convincing the scientific community that
  sulfur is an element (around 1777)
• The ratios of the masses of the second element
  that combine with a given weight of the first
  element can be reduced to small whole numbers
  (the law of multiple proportions)

How Sulfur Relates to Humans

• Sulfur is found in meteorites, volcanoes, hot
  springs, and as galena, gypsum, Epsom salts, and
  barite.
• Sulfur is essential to life. It is a minor
  constituent of fats, body fluids, and skeletal
  minerals.

Germanium Ge
Germanium (the symbol is Ge) is given the atomic
number of 32 and has the atomic mass of 72.61.
Germanium is a metalloid. It has a grayish white
color and is a solid at 298 Kelvin (25 degrees
Celsius). Germanium was discovered by Clemens A.
Winkler at Germany in 1886. Germanium was
discovered in a mineral called argyrodite.
Germanium helps people by being used in
fluorescent lights. Germanium is also used in
wide angle camera lenses and microscope
objectives.

Boron B
Uses
History
Essentials
Boron was discovered in England and france in
1808 by Sir Humphrey Dary and Louis Gay-Lussac.
Boron is used in pyrotechnic flares, an igniter
in rockets, and helps to the treatment of
arthritis.
Boron 5 B 10.811
Boron has properties which are borderline
between metals and non-metals. It is a
semi-conductor rather than a metallic conductor.

Molybdenum Mo
Molybdenum has the atomic number of 42 and the
atomic mass of 95.94. Molybdenums color has a
gray metallic luster and was discovered in Sweden
in 1781 by William Scheele. Molybdenum Is used
to improve the strength of steel at high
temperatures. It can also be found in missile
and aircraft parts. Molybdenum is often confused
with graphite and lead ore and comes from the
Greek word molybdos meaning lead
8
Cobalt Co
Cobalts atomic number is 27 and has the atomic
mass of 58.399. Cobalts color has a lustrous,
metallic, grayish tinge. Cobalt is a brittle,
hard, transition metal with magnetic properties
similar to iron. Ore deposits are located in
Zaire , Morocco, and places in Canada. Cobalt is
also present in meteorites. Cobalt was
discovered by Georg Brandt at Sweden in 1735 and
named from a German word kobald meaning
goblin or evil spirit. Cobalt is used in
Magnetic and stainless steel, and its salts are
used for the production of brilliant and
permanent blue colors in porcelain, glass,
pottery, tiles, and enamels.

VanadiumV
23 V 50.9415
Vanadium has the atomic number of 23 and the
atomic mass of 50.9451. It was discovered in 1801
by Andres Manuel del Rio and Nils Sefstrom In the
countries of Sweden and Mexico. The color is
silvery gray. With it being solid at 298 Kelvin,
here are some uses Vanadium is used as a bonding
agent in titanium steel, this makes the steel a
lot stronger!

Zirconium Zr
Uses
History
Essentials
Zirconium was discovered by Martin Klaproth at
Berlin, Germany in 1789. Its name came from
the word zargun meaning gold color
Zirconiums atomic number is 40 and has the
atomic weight of 91.224. Its color is silvery
white and can ignite spontaneously in air!
Zirconium is used in surgical appliances.
Zirconium is a metal and is used as a getter in
vacuum tubes, flash bulbs for photography, and in
explosive primers.

KryptonKr
Krypton has no color to it. You normally cant
see it since it is a gas at 298 Kelvin. In 1898
in Great Britain, There were two scientists, Sir
William Ramsay, and Morris W. Travers. They
discovered Krypton. Krypton comes from the Greek
word kryptos, meaning hidden. Krypton has an
atomic number of 36 and an atomic weight of
83.80. It is used with argon as low pressure
filling gas, and it is used in some photographic
flash lamps for high-speed photography.
12
BromineBr
Bromine has the atomic number of 35 and the
atomic mass of 79.904 (symbol is Br). Bromine
was discovered at France in 1826 by Antoine-J.
Balard. Bromine can be used in dyes, medicines,
pesticides, water purification, fumigants, and
flame proofing agents. Bromine also has some
interesting facts about it. It has a
reddish-brown, metallic luster when a solid. It
is unique because it is the only nonmetal liquid.
Some of Bromines properties include heavy,
volatile, a VERY dangerous liquid, and as a very
strong, unpleasant odor that irritates the eyes
and throat.
