---|---|---|---|---|---|
Split the nucleus to discover it contains particles with no charge that have a mass approximately equal to that of protons | Chadwick
🗑
|
||||
Reacted gases to find that all matter is made of atoms that react in whole number ratios, which led to form the billard ball model. | Dalton
🗑
|
||||
Frond that electron can have diffraction and interferance like light and other electromagnetic waves. | deBroglie
🗑
|
||||
Performed the gold foil experiment to find that atoms are mostly empty space, but have a positively charge and much mass concentrated in the nucleus, | Rutherford
🗑
|
||||
Performed the oil drop experiment which allowed him to calculate the small mass of electrons. | Millikan
🗑
|
||||
Observed the spectrakl lines of hydrogen which led him to conclude that electrons are arranged in energy levels sround the nucleus and can not be between levels. | Bohr
🗑
|
||||
discovered that two electrons can occupy the same electron cloud if they have spins in opposit directions. | Pauli exclusion principle
🗑
|
||||
Performed experiments with cathode ray tube to find that atoms contain particles with a negative charge which can leave the atom | JJ Thomson
🗑
|
||||
Mathemathically calculated all known electron orbital properties | Schrodinger
🗑
|
||||
An electron occupies the lowest energy level that can recieve it | Aufbau Principle
🗑
|
||||
Orbitals of equal energy are occupied by one electron before any orbital is occupied by a second electron, and all electrons in singly occupied orbitals must have the same spin. | Hunds Rule
🗑
|
||||
It is impossible to know both the position and velocity of an electron simultaneously | Heisenberg uncertainty principle
🗑
|
||||
indicates the main energy level occupied by an electron. | Principal quantum number
🗑
|
||||
Known as sublevels, orbitals of different shapes, (s,p,d,f) | Angular Momentum quantum number
🗑
|
||||
Indicates the orientation of an orbital around the nucleus. | Magnetic quantum number
🗑
|
||||
Indicates the two possible spin states of an electron in an orbital | Spin quantum number
🗑
