1. Welcome to Chemistry!
(with Ms. MacInnes)

2. What is Chemistry, you ask?
The study of the composition, structure and properties of matter
Example: Water
Composition: 2 hydrogen atoms and one oxygen atom
Structure:
Properties: bp 100oC, tasteless, liquid at room temperature, clear...etc.

3. Lucky Chemists! There are millions of chemical substances
New ones are manufactured regularly
We must know their properties to safely deal with them!

4. Lab Safety is Important

5. We will also learn about…
Acids, bases and neutralization
Acid Rain
Nomenclature
Types of Reactions
Balancing Equations
Rates of reactions
…all with a smile!

6. Of course we will see explosions…on video!
Brainiacs!

7. Let’s Get Started! Label the periods and groups
Also label the following:
Alkali Metals
Alkaline Earth Metals
Halogens
Inner Transition Metals
Noble Gases
Transition Metals
Periodic table

8. In 1869, Russian chemist Dmitri Mendeleïev, established the first periodic table of elements, classifying the elements in ascending order according to their atomic mass.

20. Each square represents a different element
Each square represents a different element. Generally, it will indicate the symbol, atomic number and atomic mass of the element.
