A quick review of

Atoms and Molecules

Lesson 2: What Are Compounds?● Read pg. E46-47● What is the periodic table?

○ table of elements○ In order of increasing atomic number

■ Number of protons in nucleus ○ Grouped by similar properties

■ Metals■ Nonmetals■ Metalloids - has properties of metals AND nonmetals■ (Artificially Made)

Compounds● Read p.E48-E49● What is a compound?

○ a substance made of the atoms of two or more elements● What does a chemical formula show?

○ The elements and the number of atoms of each element in one molecule of a compound

○ Example:■ Table Salt = NaCl

● 1 sodium atom● 1 chlorine atom

● When atoms join to form compounds, they undergo a chemical change.
