  What Is an Atom? An atom is the smallest unit of an element that retains the chemical properties of that element. Everything around us—from the air we breathe to the stars in the universe—is made of atoms. They are the fundamental building blocks of all matter. The word "atom" comes from the Greek word atomos , meaning "indivisible." While scientists once believed atoms could not be divided, modern physics has shown that atoms are made up of even smaller particles called protons, neutrons, and electrons . Today, atoms are one of the most important concepts in chemistry, physics, biology, and modern technology. The History of Atomic Theory Our understanding of atoms has evolved over thousands of years. Democritus (Around 400 BC) The ancient Greek philosopher Democritus proposed that all matter was made of tiny, indivisible particles called atoms.

  Today We Start Learning About Quantum Mechanics  Quantum mechanics is one of the most important and fascinating branches of modern physics. It describes how matter and energy behave at the smallest scales—atoms, electrons, photons, and other subatomic particles. Unlike classical physics, which explains the motion of everyday objects, quantum mechanics reveals a world where particles can exist in multiple states, behave like waves, and even influence one another across vast distances. Developed during the early 20th century, quantum mechanics transformed our understanding of the universe and became the foundation of many modern technologies, including computers, lasers, semiconductors, MRI scanners, and quantum computers. What Is Quantum Mechanics? Quantum mechanics is the branch of physics that studies the behavior of particles at the atomic and subatomic level. At these incredibly small scales, the laws of classical physics no longer apply. Instead, particles follow a compl...
