The comparison of number of electrons in a normal atom with the number of protons in the nucleus.
Explanation of Solution
Introduction:
An atom is composed of the subatomic particles electrons, protons and neutrons. The protons and neutrons remain in the nucleus but the electron moves around the nucleus in different orbits.
The net charge of the normal atom remains zero. The normal atom remains in neutral state. The electrons are the negatively charged particles, protons are positively charged and neutrons are uncharged particles.
The number of electron in an atom remains equal to the number of proton in the nucleus for normal atom. If the numbers of electrons are not same as the number of proton in the nucleus then the atom may become positive or negative in nature.
Conclusion:
Thus, the number of electron and number of proton is equal in the normal atom
