They all contributed to the chemistry and physics world

Dalton
is known for his atomic theory
A. Dalton's Atomic Theory
matter is made of atoms and they are indivisible and indestructable
all atoms of the same element are identical in mass and properties
-compounds are made by the combination of 2 or more different atoms.
a chemical reaction is the rearrangement of atoms
Thomson
-studied cathode rays
-discovered corpuscles ( now known as electrons )
A. Thomson's Plum Pudding Model
electrons are embedded in a positive sphere
Rutherford
was the student of Thomson
-discovered the nucleus
A. Rutherford's Atomic Theory
-the atom's whole mass is centered in the nucleus
-positively charged particles are present in the nucleus
electrons revolve around the nucleus in different orbits
- Mendeleev
  *Mendelevium is an element from the periodic table
  -a.k.a father of the Periodic Table
  -made a new periodic table according to increasing atomic weight
  -predicted new elements
  -Mendelevium was named after him in his honor
Bohr
-contributed to the Manhattan project
-established CERN, a particle physics research facility
-Bohrium, an element, was named after him
A. Bohr's Atomic Theory
-electrons travel in separate orbits
-number of electrons determine the properties of the element
B. Quantum Theory
-an electron can be viewed as a particle or wave but not at the same time
Schrodinger
A. Quantum Numbers
-describes the probability of the electron's location at a certain time
-there are 4 orbitals: s, p, d, f
