The basic building blocks of matter are atoms. Everything around us, whether it is a solid, liquid, or gas, is made up of these tiny units.
Atoms themselves consist of three main particles: protons, neutrons, and electrons. Protons and neutrons reside in the nucleus, the center of the atom, while electrons orbit around the nucleus in various energy levels.
Protons carry a positive charge, neutrons have no charge, and electrons carry a negative charge. The balance of these charges and the arrangement of these particles give rise to different elements and, subsequently, all matter we see in the universe.
Understanding atoms and their interactions is fundamental in the field of chemistry and helps explain the properties of materials, reactions, and the formation of molecules.
