Elements (Chemical Elements)

Chemical elements are pure substances made of only one type of atom, which is the basic building block of matter. Each element has unique properties and is identified by a specific symbol and atomic number, representing the number of protons in its atoms. Elements combine in various ways to form all materials around us, from air and water to metals and plastics. The periodic table arranges these elements based on their properties, helping us understand how they behave and interact. Elements are the fundamental components of everything in the universe, from the smallest particles to massive stars.
