Atoms

Atoms are the basic building blocks of matter and the fundamental units of chemical elements. They consist of three main types of subatomic particles: 1. **Protons**: Positively charged particles found in the nucleus (the central part) of the atom. 2. **Neutrons**: Neutral particles (no charge) that also reside in the nucleus alongside protons. 3. **Electrons**: Negatively charged particles that orbit the nucleus in energy levels or shells.
