1 Periodic Table

2 Periodic Table Periodic Table: lists all known elements in rows and columns based on patterns of similar properties

3 Periodic Table Periodic Table: lists all known elements in rows and columns based on patterns of similar properties Element: pure substance that cannot be broken down into simpler substances e.g. oxygen, gold

4 Periodic Table Periodic Table: lists all known elements in rows and columns based on patterns of similar properties Element: pure substance that cannot be broken down into simpler substances e.g. oxygen, gold Compound: pure substance made up of elements bonded together e.g. water, baking soda

5 Periodic Table Periodic Table: lists all known elements in rows and columns based on patterns of similar properties Subatomic particles: the pieces that make up an atom (protons, neutrons, electrons)

6 Periodic Table Periodic Table: lists all known elements in rows and columns based on patterns of similar properties Subatomic particles: the pieces that make up an atom (protons, neutrons, electrons) Proton: positively charged particle

7 Periodic Table Periodic Table: lists all known elements in rows and columns based on patterns of similar properties Subatomic particles: the pieces that make up an atom (protons, neutrons, electrons) Proton: positively charged particle Neutron: particle with no electric charge

8 Periodic Table Periodic Table: lists all known elements in rows and columns based on patterns of similar properties Subatomic particles: the pieces that make up an atom (protons, neutrons, electrons) Proton: positively charged particle Neutron: particle with no electric charge Electron: negatively charged particle

9 Periodic Table Periodic Table: lists all known elements in rows and columns based on patterns of similar properties -elements are arranged in order by atomic number

10 Periodic Table Periodic Table: lists all known elements in rows and columns based on patterns of similar properties -elements are arranged in order by atomic number Atomic Number: number of protons in atoms of that element

11 Periodic Table

12 Periodic Table Atomic Numbers: Oxygen (O) = ?

13 Periodic Table Atomic Numbers: Oxygen (O) = 8

14 Periodic Table Atomic Numbers: Oxygen (O) = 8 Helium (He) = ?

15 Periodic Table Atomic Numbers: Oxygen (O) = 8 Helium (He) = 2

16 Periodic Table Atomic Numbers: Oxygen (O) = 8 Helium (He) = 2 Gold (Au) = ?

17 Periodic Table Atomic Numbers: Oxygen (O) = 8 Helium (He) = 2 Gold (Au) = 79

18 Periodic Table Period: a horizontal row

19 Periodic Table Group (Family): a vertical column

20 Periodic Table Group (Family): a vertical column Alkali Metals: group IA Alkaline Earth Metals: group 2A Halogens: group 7A Noble Gases: group 8A

21 Periodic Table Staircase: a stepped line separating metals and non-metals

22 Periodic Table Staircase: a stepped line separating metals and non-metals Metals: to the left Non-metals: to the right Metalloids: around the staircase
