An atom is composed of three types of subatomic particles: protons, neutrons, and electrons.

1. Protons: These are positively charged particles located in the nucleus (center) of an atom. The number of protons in an atom determines the atomic number and the type of element it is. For example, an atom with one proton is hydrogen, an atom with two protons is helium, and so on.

2. Neutrons: These are neutral particles, meaning they have no charge. They are also located in the nucleus of an atom. The number of neutrons in an atom contributes to its atomic mass. Neutrons and protons together are called nucleons.

3. Electrons: These are negatively charged particles that orbit the nucleus in energy levels often visualized as a cloud around the nucleus. The number of electrons in a neutral atom is equal to the number of protons. Electrons are much smaller than protons and neutrons, and they are involved in chemical reactions and bond formation between atoms.
