Welcome to Chemistry!

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.

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 explosionson video!

• Brainiacs!

7
Lets 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

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

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