Welcome to Chemistry! (with Ms. MacInnes)

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!

Lab Safety is Important

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

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

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

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

The periodic table Groups Periods

Alkali metals

Alkaline earth metals

Transition metals

Lanthanides

Actinides

Other metals

Noble gases

Halogens

Hydrogen

Other non-metals

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.
