Q. 1. On the basis of Thomson’s model of an atom, explain how the atom is neutral as a whole.
According to Thomson’s model of an atom, an atom consists of a sphere of a positive charge.
The positive charge in the atom is spread all over like the red edible part of a watermelon, while the electrons are studded in the positively charged sphere, just like the seeds in the watermelon.
As negative and positive charges are equal in magnitude, they balance each other and thus the atom becomes electrically neutral as a whole.
