Transcript of Chemistry Timeline
Used in oxygen tanks and we breathe it.
Platinum is used to make jewelry.
Used to make very strong magnets and deep blue pigment.
John Dalton (1790)
His theory was that elements consisted of atoms
Used as a coating for car parts
Used in the chemical industry and is needed by the nervous system
Our nerves and muscles depend on certain minerals called electrolytes. Sodium, along with potassium, is a type of electrolyte.
also contain potassium
Used as a sterilization agent for cleaning wounds
Used to make glass
Creates a semi-conductor used in computers
Makes drink cans
Makes infrared detectors and batteries that can work below zero
Used to make
Used in light bulbs
His theory was electrons inside an atom could show and were not invisible.
His theory stated electrons traveled around an atom's
nucleus in orbit.
Niels Bohr (1913)
UsEd To MaKe SuPeR hArD mEtAlS
Used in smoke detectors
Ernest Rutherford (1909)
His theory stated the atom has a central nucleus and orbiting atoms.
E Schrodinger & W Heisenberg (1950)
Their theory concluded that electrons were systematically distributed in orbitals
used in radium painted
watches and clocks
used to make magnets
Used to conduct radio therapy
Makes jewlery look shiny
Marie Curie (1903)
Radioacticity comes from the center of the atom.
Used to make darts and cutting tools
Platinum is the rarest and the heaviest out of all the precious metals on Earth
Cobalt gets its name from the German word for 'evil spirit'
Nickel can be found in meteorites
Bismuth has a half life of 19 quadrillion years
Nitrogen makes up most of the air and makes the
colors in the aurora borealis
Excited oxygen makes the
colors in the aurora
Tungsten has the highest melting point of all the metal elements
Chromium is used to color
Sodium can be found in the sun and other stars
Rhodium is the rarest non-radioactive metal on Earth
Seafood, kelp, and plants grown in iodine-rich soil are all natural food sources of iodine
When silicon is combined with oxygen, it creates sand
There is a lot of aluminum
on the Moon
on contact with water, as do all alkali metals
cesium atomic clock
(gives really acurate time)
Indium is the 61st most common element in the Earth's crust
Samarium was the first element to be named after a person
1.6% of Mar's atmosphere contains Argon and it has a half life of 35 days
Exposure to Radium can cause
cancer and is 1 million times
more radioactive than Uranium
Hafnium is used in nuclear reactors
Astatine can be made in nuclear reactors
Astatine is radioactive!
is named after the
