Electrons

Electrons The identity of the electron goes back to 1752 when Benjamin Franklin’s discovery set other scientists out trying to see if electrical energy could travel through gases other than the atmosphere. This was proven to be true and that electrical energy and particle movement also produced a ray… even when it was not moving through any gas. This surprised early investigators because they thought the ray was associated with the gas instead of an entity in and of itself! Tests also showed that the ray was blocked from reaching the Anode (+ charged end) when something was in its path. So they reasoned the ray originated from the Cathode (- charged end) and named it a cathode ray. The experiments where therefore done in a cathode ray tube. Further experimentation proved that magnetic fields could deflect a cathode ray. The speed of of this ray was found to be much slower than the speed of light. ray, cathode, particles, electrical, particle, charge, value, through, thomas, speed, millikan, mass, magnetic, light, increment, greater, gas, formula, energy, end, electron, deflection, charged, calculated, because, beam, wouldn’t, using, tube, trying, true, travel, thought, therefore, tests
