What are canal rays?
The Canal rays are positively charged radiations consisting of particles which have a charge equal in magnitude but opposite in sign to that of the electron. The mass of a canal ray particle is 2000 times as that of the electron. This particle is known as proton.
If an atom contains one electron and one proton, will it carry any charge or not?
On the basis of Thomson's model of an atom, explain how the atom is neutral as a whole.
