Understanding the Atom

The video tutorial explains that matter is composed of atoms, which are tiny particles proposed by Democritus. Atoms consist of subatomic particles: protons, neutrons, and electrons. Each element has a unique atomic number and mass, determined by its protons and neutrons. Elements are classified into metals and non-metals and are organized in the periodic table, which provides detailed information about each element.
