Understanding Subatomic Particles

The video explains that all matter is composed of atoms, which are the fundamental building blocks. It highlights the contributions of scientists to our understanding of atoms, which consist of subatomic particles: protons, neutrons, and electrons. Protons are positively charged and located in the nucleus, neutrons have no charge and are also in the nucleus, while electrons are negatively charged and orbit the nucleus.
