Chemistry - The Atom
Fichas del conjunto (12)
- 1Which Did Dalton Discover About Matter?That all matter is made of small particles called atoms and are indivisible
- 2What Did Crooke Discover With His Tube?That cathode's are connected to the negative electrode and anode are connected to the postive electrode
- 3What Did He Discover Came From The End Of The Tube?He Discovered that radiation came from the end of the tube connected to the negative cathode end of the battery
- 4What Was The Radiation Called?Cathode rays
- 5What Do Cathode Rays Do?They cast shadows, Cause the glass to glow (fluoresce), Turn the paddle wheel and the rays are made of particles
- 6What Did J.J Thompson Discover?J.J Thompson Discovered that a hole in the anode allowed beams of rays to pass through and that these beams could be deflected by electric plates and therefore made of negative particles
- 7What Ratio Did He Calculate?He calculated the ratio of charge to mass for electron (e/m)
- 8Who Named The Electron?G. Stoney
- 9What Are Cathode Rays?Cathode rays are streams of negatively charged particles called electrons. They travel in straight lines from the cathode to the anode, are deflected by electric and magnetic field and have sufficient energy to move a small object such as a paddle whee
- 10What Was Robert Millikan Famous For?He was famous for the oil drop experiment which measured the charge on the electron. He took measurements and calculated the charge on the electron
- 11What Does Thomsons "Plum Pudding" Model Of The Atom Look Like?The atom is a sphere of positive charge with the negative electrons embedded randomly
