* Protons: Positively charged particles found in the nucleus of an atom.
* Neutrons: Neutrally charged particles also found in the nucleus.
* Electrons: Negatively charged particles that orbit the nucleus in a cloud-like region called the electron cloud.
Here's a simple analogy: Imagine an atom as a tiny solar system.
* The sun would be the nucleus, containing the protons and neutrons.
* The planets would be the electrons, orbiting the nucleus.
Important Notes:
* The protons and neutrons are made up of even smaller particles called quarks.
* Atoms can be further divided into even smaller particles, like quarks and leptons, but these are not typically considered the building blocks of atoms in basic chemistry.
* The arrangement of these particles determines the atom's properties and how it interacts with other atoms.
