The Particle Model

• Matter


  Everything around you that has mass and takes up space
• Particles


  Tiny things that matter is made up of and move
• Particles are so small, you can't see them even with a microscope
• Gap fill

  Matter is made up of tiny particles. They are so small you couldn't even see them with a microscope! Particles are always moving.
• In a substance, every particle is the same
• Substances and their particles

  • Magnesium is made up of magnesium particles
  • Iron is made up of iron particles
  • Gold is made up of gold particles
• Property


  A quality or characteristic of something
• Properties of the different states of matter


  • Liquid
  • Solid
  • Gas
• In each state, the particles are the same


  But the way they're arranged changes
• What its particles are like


  • How the particles are arranged
  • How the particles move around
• There are hundreds/millions of materials. Materials are made up of particles.
• A substance has the same properties all the way through.
• In a substance, all the particles are the same.
• The particles of different substances are different.
• The properties of a substance describe its behavior.
