Definition and Meaning of Protons, Neutrons, and Electrons
Protons, neutrons, and electrons are fundamental particles that make up atoms, the basic units of matter. Understanding these particles is essential for grasping the principles of chemistry and physics. Each particle has distinct properties:
- Protons: Positively charged particles found in the nucleus of an atom. The number of protons determines the atomic number and identity of the element.
- Neutrons: Neutral particles that also reside in the nucleus. Neutrons contribute to the atomic mass and play a key role in the stability of the nucleus.
- Electrons: Negatively charged particles that orbit the nucleus in electron shells. The number of electrons typically equals the number of protons, resulting in a neutral atom.
These three particles interact to form the various elements and compounds that make up the universe.
