* Protons: Located in the nucleus, protons carry a positive (+) charge. They are one of the fundamental building blocks of matter.

* Neutrons: Also located in the nucleus, neutrons carry no charge (they are neutral). They help stabilize the nucleus and contribute to the atom's mass.

* Electrons: Orbiting the nucleus in a cloud-like region called the electron cloud, electrons carry a negative (-) charge. They are much smaller and lighter than protons and neutrons.

Key Points:

* The number of protons determines the element. For example, all carbon atoms have 6 protons.

* The number of neutrons can vary, resulting in isotopes. Isotopes of the same element have the same number of protons but different numbers of neutrons.

* Atoms are normally electrically neutral. This means they have an equal number of protons and electrons.

* The arrangement of electrons in the electron cloud determines the atom's chemical properties.
