1. Matter and Its Particles

Key Concepts & Definitions

  • Matter : Everything that has volume and mass.
  • Corpuscular model : A scientific model based on the idea that matter is made of particles.
  • Atom : The smallest particle of matter that cannot be divided chemically.
  • Molecule : A group of two or more atoms chemically bonded together.

2. Corpuscular Model and Democritus

β˜… Must-know

  • The corpuscular model is based on four statements:
    • Matter is composed of extremely small particles
    • The particles are constantly moving
    • When temperature increases, particle motion increases
    • Particles can be held together by attractive forces

Further detail

  • Democritus was a Greek philosopher who is considered the first thinker to suggest that matter is made of particles.

  • The word atom comes from the Greek word β€œatomos,” meaning indivisible, and Democritus used it to identify particles of matter.

Memory Hook

Higher temperature causes faster particle motion.
