(a) If an atom contains one electron and one proton, will it carry any charge?
(b) On the basis of Thomson's model of an atom, explain how the atom is electrically neutral.

Expert Answer
(a)Since no. of protons = no. of electrons
Hence, there is no charge on the atom and so the atom is neutral.
(b)The positive charge due to protons and negative charge due to electrons balance each other because they are equal in magnitude and hence the atom is neutral.
