Title: Welcome to Chemistry!


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 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

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.

9
The periodic table
  • Groups
  • Periods

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