Question
Answer
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  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
