Detailed explanation-1: -If atoms are made of neutral particles then there will not be any electromagnetic forces. Therefore there will not be tension, friction and normal reaction but gravitational force exists.

Detailed explanation-2: -When an atom is electrically neutral, it means that the overall charge of the atom is zero. Atoms are made up of positively charged particles called protons and negatively charged particles called electrons as well as non-charged particles called neutrons.

Detailed explanation-3: -It consists of many elementary particles-nucleons-the main of which are protons and neutrons that move in the field of nuclear forces and continuously change their state from that of charged particle (proton) to neutral particle (neutron) and vice versa.

Detailed explanation-4: -So an atom is said to be electrically neutral when it has the same number of protons and electrons and the number of neutrons doesn’t affect the charge of an atom.

Detailed explanation-5: -Hence, atoms are electrically neutral because they contain an equal number of protons and electrons.
