Welcome to Magnet Brains, a channel offering free quality education by Self Himmat, discussing Class 11th Chemistry Chapter Number Tu on the Structure of Atom. Thomson discovered the electron and its charge by mass ratio, while Millieux conducted the Propane Oil Drop experiment to determine the charge on an electron, crucial for understanding electron properties.
Insights
Sir J Thomson's experiments led to the discovery of the electron and the calculation of its charge-to-mass ratio, which was found to be 1.75 * 10^11 Coulomb/K. This groundbreaking research paved the way for further investigations into the structure of the atom.
The Milikan Oil Drop Experiment, conducted by Million Sir and Militant Sir, determined the charge on a single electron to be 1.6 * 10^-19 Coulombs. This experiment showcased that the charge on any oil droplet was a multiple of this value, emphasizing the quantized nature of electric charge and fundamental properties of electrons.
