• # Antoine Lavoisier

Father of Modern Chemistry. Found and termed oxygen and hydrogen and put together the first extensive list of elements.
• # Joseph Peoust

Formulated his law of definite proportion. Pointed out copper carbonate must always be made from the same fixed proportions of copper crbon, and oxygen.
• # John Dalton

All matter is extremely small particles and a given element are identical, having same size, mass,and chemical properties.

Avogadro law states that equal volume of gases at the same temp. and pressure contain the smae number of molecles
• # Civil War

The Civil War lasted four years. It was the 11 southern slave states known as the Confederates and the other 25 states known as the Union. After the four years the Union won and slavery was outlawed.
• # Assassination of Abe Lincoln

• # American Football

Football was invented by a guy named Walter Camp. He got the idea from William Ebb Ellis who was playing a game of soccer when he picked up the ball and started to run with it, therefore breaking the rules and giving Camp the idea for the game.
• # William Crookes

Produce cathode- ray. Negatively charged by study of deflection.
• # JJ Thompson

Particles were a universial component of matter. there must be postively charged particles which carry the mass of the atom.
• # Ernst Rutherford

The positive charge and mass of an atom were conantrated in the center and only made up a small fraction of the total volume
• # Max Planck

A professor of theortical physical in Berlin showed that when vibrate atoms strong enough, you can measure the energy only in discrete units. He called these energy packets quaantal
• # Henri becquerel

Discovered radioactivity and won Note Prize in Physics.

• # Albert Einstein

Published the famous equation E=mc^2 and the theory of general relativity
• # Henry Moseley

Fequencies of x-rays should depend on the charge on the nucleous emitting there x-rays. atomic number positive charges.
• # Robert Millikan

Charge on a oil-drop wsa always a multiple of 1.59 X10^-19 Coulombs. He proved Thompson's hypothesis that the mass of an election is atleast 1,000 times smaller than the smallest atom
• # Colored Nail Polish

Colored nail polish was first invented in the 1920's and founded by Revlon. The Chemical compostion has changed, but the main formula is the same.
• # Niels Bohr

Physicist who made fundamental contributions to understanding atomic structure and quantum mechanics
• # Erwin Schrodinger

Took Broglie and other ideas and made and equation solving the equation can predict the properties and reactivities of atoms and molecule.

proved that neutrons, neutral particles in the nucleous that made up apporximately half the mass of an atom did exist.
• # Werner Heisenberg

Creation of quantum mechanics and discovery of allotropic form of hydrogen
• # Louis deBroglie

Extensions of wave mechanics
• # The Buckle

It was founded in the year 1948. It is a retail store, and there are 423 locations of the store
• # The first computer company

The first computer company was Electronic Controls Company. Founded by j.Presper Eckert and John Mauchly.
