Take out your periodic table

Take out highlighter and pencil/pen

You will be writing on your personal paper

BASICS OF THE PERIODIC TABLE

1. Columns that go up and down are called groups and or families (18)

2. Sections that go from side to side are called periods and are also referred to as energy levels (7)

3. The periodic table organizes all known information of the elements that we have on Earth and categorizes them by metals, nonmetals, and metalloids

Groups and periods

• Groups are the vertical columns on the periodic table.

• Periods are the horizontal rows.

• Elements in the same group will have the same characteristics because they have the same # of valence e-.

• Those elements in the same periods (rows) will have the same number of electron energy levels.

Group Names

• Group 1 = Alkali Metals

• Group 2 = Alkaline Earth Metals

• Groups 3-12 = Transition Metals

• Group 17= Halogens

• Group 18= Noble Gases
