Elements, Compounds and Mixtures

​U1L1

​KEY WORDS

​Element

Compound

Mixture

Pure Substance

Chemical Bond​

​

​Objectives

1. Compare elements, compounds and mixtures

2. Examine chemical bonds

3. Compare solids, liquids and gases

Elements

​

• There are more than 100 different different elements

• An element is a type of atom with the same number of protons

• The term element is also used to describe a substance that is made of the same type of atom

• ​Elements are pure chemical substances. 

​Compound

• Elements can chemically combine to form new, pure chemical substances. 

• A chemical substance that is made of two or more different elements that chemically combine together is called a compound

• The force between compounds is STRONGER than between mixtures​

​Mixture

• A compound is NOT the same as a mixture

• A mixture is a physical combination of two or more different chemical substances.

• A compound is a chemical combination of two or more different chemical substances (specifically, elements)

• Unlike an element and compound, a mixture is NOT a pure chemical substance

• Element

• Compound

• Mixture

• Molecule

Multiple Choice

Mixtures have a stronger force between them than compound

• True

Chemical Bonds

• Elements chemically combine by forming chemical bonds

• A chemical bond is an attraction between atoms

Chemical Bonds

• When atoms connect to each other by a chemical bond, a molecule is formed

• A molecule is a chemically pure substance that is made of two or more atoms bonded together. The atoms can be of the same or of different elements

• A compound is a molecule that is made of two or more different elements

• All compounds are molecules, but not all molecules are compounds. ​

Multiple Choice
