Science Section 1: The Atom By: Natalie P., Gurneet, Karina, and Nazanin

What are the four basic elements? Fire, Water, Earth, Air

Who was credited with the discovery of electrons? J.J. Thomson

WHAT WAS THE EXPERIMENT THAT JAMES FRANCK AND GUSTAV HERTZ EXECUTED? FIRING ELECTRONS THROUGH A GAS OF MERCURY IN A HEATED VACUUM TUBE

LOUIS DE BROGLIE WAS THE FIRST TO PROPOSE MATTER COULD BE TREATED AS HAVING WHAT CHARACTERISTICS? WAVE-LIKE CHARACTERISTICS

WHAT MECHANIC THEORY OR PRINCIPLE STATES THAT OBJECTS CAN BE DESCRIBED AS HAVING A POSITION AND VELOCITY THAT ARE BOTH WELL DEFINED? Newtonian Mechanics

For the young double-slit experiment, what intensity light was needed? Low Intensity

Who were the Pauli Exclusion Principles proposed by? Wolfgang Pauli
