From Particles to
Solutions
Chemistry 01
Learning Goals!!
• I will be able to explain the particle theory of matter.
• I will be able to classify matter using the terms: pure substance,
element, compound, mechanical mixture and solution
What is CHEMISTRY!?
• The study of matter and the changes it undergoes
Matter …
• Anything that has mass and takes up space.
The Particle Theory of Matter
•
•
•
•
•
All matter is made up of different kinds of particles
Different substances are made up of different types of particles
Particles are in constant random motion
Particles move faster when heated, and slower when cooled
Particles attract each other
Lists
• Create a list of 15-20 items you’ve used, eaten, seen, etc. in the
last day or two.
• Save this list for later.
Pure Substances
• Made up of only one type of particles
• Any element from the Periodic Table
• Any compound (like distilled water, carbon dioxide)
Mixtures
• Made up 2 or more types of particles
• Mechanical mixture – you are able to see the different particles
• pizza, oil and vinegar, cereal
• Solution – a mixture where you can’t see the different particles and you can see
through it
• apple juice, air in this room
• Alloy – a solid solution of two or more metals.
• i.e. Bronze -> Copper + Tin
Classification of Matter
MATTER
PURE
SUBSTANCES
Can combine to form
MIXTURES
ELEMENTS
COMPOUNDS
SOLUTIONS
i.e: H, O, C
i.e: H2O, NaCl
i.e: H2O + salt
MECHNICAL
MIXTURES
i.e: H2O +
raisins
Learning Goals Revisited
• I will be able to explain the particle theory of matter.
• I will be able to classify matter using the terms: pure substance, element,
compound, mechanical mixture and solution
Task
• Go back to your list. Try to determine what type of matter each item is. i.e.
if you had pizza it would be a mechanical mixture.
• Share list with your partner
• Complete poem Qs
• Textbook p178 #2-6, 8.
