An element is matter made up of only one
kind of atom All matter is made up of elements
Examples: oxygen and nitrogen are in the air we breath & metals like aluminum are used to make many products we use everyday like soda cans
What is an element?

A chart that organizes and displays all the elements Elements are represented on the table with symbols
One capital letter OR one capital and one lowercase letter
Example: O: Oxygen & Al: Aluminum What other information can be seen on the periodic
table? Atomic number Atomic mass Metal, nonmetal, metalloid Solid, liquid, gas
The Periodic Table

Made up of more than one kind of atom Made up of more than one kind of element Example: Water
H20 Made up of the elements hydrogen and oxygen
What are compounds?

When the atoms (elements) that make up a
compound come together a chemical change occurs
This means the elements cannot be separated from each other very easily
What are compounds?

Compounds are represented by formulas
which include letters and sometimes numbers These formulas tell us….
What elements are in the compound How many atoms of each element
Let’s try it! What is NaCl made up of? What is CO2 made up of?
What are compounds?
