-
Father of modern science
Came up with first atomic theory
1) Everying is made of atoms
2) Atoms are indestructible
3) Atoms interact with other atoms mechanically
4) There is a finite amount of atoms always in motion. -
Defied what elements are.
"Any substance that can't be broken down into two or more substances is an element" -
Law of conservation of mass
-
Atomic theroy
1. All mater made of atoms
2. Atoms are indivisible and indestructable
3. All atoms of a given element are identicle in mass and properties
4. Compounds formed by two or more different kinds of atoms
5. Chemical reaction is a reconfigurationn of atoms -
- fourmulated perodic table of chemical elements
- Arranged by atomic weight
- Sorted by properties
-
- Discovered electron
- Plum pudding model in 1904
-
- Figured out radiation
- Planck radation formula
- Energy emited in diferent wave lenths
-
Proved the proton exists and is positively charged using cathode rays.
-
- Discoved electrons charge independantly
- Used the oil drop experiment
- 1.592 x 10-19 charge of electrons
-
- Gold foil experiment
- Discovered the nucleus
- Came up with rutherford model
-
- Quantum theroy
- Explained the inside of atoms
- Atomic model
- Electrons travel in seperate orbits
-
- Proved nuetrons existance
- Atom number determed by protons
-
- Nobel prize in physics
- used math to describe the likely-hood of finding an electron in a certan position
- "Electron cloud"
