C Nucleus is composed of neutrons and protons
- An atom is composed of protons, electrons and neutrons. Hydrogen is the only atom that doesn't have a neutron.
- Both neutrons and protons are situated at the center of an atom and this dense region is called nucleus. Electrons revolve around the nucleus in a specific region called orbit.
- Protons are positively charged and electrons are negatively charged subatomic particles. Neutrons doesn't have any charge.
- Charge of an atom depends on the number of electrons and protons in them. If they are equal, then such an atom is termed as neutral atom.
