- 6. An atom consists of neutrons, protons and electrons. Protons and neutrons are present inside the nucleus. Nucleus has no charge.
- 7. They revolve in circular orbits around the nucleus. They are negatively charged. Mass = 9.1 x 10-31kg
- 8. Protons are present inside the nucleus. They are positively charged. Mass = 1.67x10-27kg
- 9. Neutrons are also present inside the nucleus. They are neutral. Mass = 1.676x10-27kg
- 10. Nucleus is the center part of an atom. It consists of both protons and neutrons. Nucleus is positively charged.
