In this model, the positive charge of the atom is spread out uniformly throughout the atom, while the negatively charged electrons are scattered within it. The atom is neutral as a whole because the positive charge of the atom balances the negative charge of the electrons.
On the basis of Thomson’s model of an atom, explain how the atom is neutral as a whole. Read More »
An atom with one electron and one proton will not carry any charge and will be neutral. This is because an electron has a negative charge, while a proton has a positive charge, and the magnitude of each charge is equal. The two charges cancel each other out, resulting in a neutral atom.

Canal rays, also known as positive rays, are positively charged ions that move towards the negative electrode (cathode) in a cathode ray tube. They were discovered by Eugen Goldstein in 1886. These rays are formed when the residual gas in the cathode ray tube is ionized by the high voltage applied across it. Canal rays helped scientists understand the existence of positively charged particles later identified as protons.
