The document provides an overview of atomic structure, including the components of atoms (electrons, neutrons, and protons) and their significance in understanding matter. It discusses the properties and classifications of matter, emphasizing the three states (solid, liquid, gas) and the differences between pure substances and mixtures. Additionally, the document highlights various physical and chemical properties, phase changes, and the concept of diffusion.

REVIEWER OF SCIENCE
• In Latin word atom is (atomus).
• John Dalton first discovered of atom.
• Smallest Particale of matter. Size of
angstrong
• atoms make up everything around us.
• instrument use to see atoms its called STM
• Molecules two or more atoms combined
together in specific
Arrangement
• Compound are make up of different type
of atoms

6. Properties
of matter
Two type of
properties
Chemical Properties
 flammability
 toxicity
 acidity
 reactivity
 Physical properties include Viscosity
 Color
 Hardness
 Maleability
 Flexibility
 Texture
 Conductivity
 Viscosity

7. Phase Change
 Sublimation
 Deposition
 Freezing
 Melting
 Condensation
 Vaporation

8. Diffusion
 This is because in hot
water, the water molecules
have more energy and are
moving faster than the
molecules of cold water.
This makes it easier for the
dye to get mixed
throughout the hot water
