1. Introduction of Chemistry
Objective:
You will be able to understand and explain the foundation the science of chemistry

2. Chemistry
The science of the composition, structure, properties, and reactions of matter

3. What is matter
Matter-anything that has mass and exists as a solid, liquid, or gas

4. All Matter exists in 3 states
Solid-matter with a definite shape and volume: Compressible
Liquid-matter with no definite shape but has volume: Non- Compressible
Gas-matter has neither shape nor volume but has mass: Compressible

5. 3 States of Matter
All matter can be found in 1 of the 3 states (mainly dependent upon temperature)
Gas and liquid TRANSITION --Evaporation (up) or Condensation (down)
Liquid and solid TRANSITION --Melting (up) or Freezing (down)
Solid to Gas TRANSITION-----Sublimation- process by which a material goes through a solid to gas NO Liquid phase (up) Deposition gas to solid (NO Liquid phase)
REMEMBER TEMPERATURE OF MATTER DOES NOT CHANGE AS IT GOES THROUGH STATE CHANGE

6. Intro to Matter
Properties both physical and chemicals come from the actual structure of the element’s atom or atomic design

7. Purest from of matter What is an “Element”?
Element-PUREST FORM of MATTER Elements cannot be reduced to simpler substances by normal chemical means: each element has its own unique properties/characteristics

8. 2 main Properties of matter
Physical – Based on how it looks
Chemical- Based on how it reacts with other elements

9. Physical Properties
Properties that are observed with the senses and can be found without destroying matter

10. Chemical Properties
Properties that show how matter reacts to other matter; end matter is different than original matter and has unique physical properties

11. What makes up Matter?
ATOMS-Smallest division of an element that retains all the physical and chemical characteristics of the element
Molecule- 2 or more atoms joined together

12. 3 major parts of an atom Proton- “+” charge found in nucleus
Neutron- “neutral” charge particle in nucleus
Electron- “-” charge particle found around nucleus

13. Atoms were first thought of by the Greeks over 2,400 years ago
Atoms were first thought of by the Greeks over 2,400 years ago. Atom name comes from Greek meaning “indivisible”
