This document discusses the basic units that make up all matter: atoms, molecules, elements, compounds, mixtures and solutions. It defines each term and provides examples. Atoms are the smallest unit of matter that cannot be divided further. Molecules are made of two or more atoms combined together. Matter is made up of elements, compounds, mixtures and solutions. Elements are molecules made of the same type of atom, while compounds are molecules made of two or more different types of atoms combined chemically. The document then gives examples of common molecules and compounds like methane, oxygen gas, and ammonia to illustrate the concepts.

1. Atoms, Molecules,
Elements, Compounds,
Mixtures & Solutions!

2. •ATOM
The smallest building unit of matter which can’t
be divided.

3. •MOLECULE
Made from more than one atom
combined together.

5. •Matter is divided into 4 groups
*ELEMENTS
*COMPOUNDS
*MIXTURES
*SOLUTIONS

6. •ELEMENT
Its molecule is made of the same type of atom
combined together.

7. •COMPOUND
A kind of matter made of a chemical combination
of two or more types of atoms.
Every compound has a formula that shows how
many atoms of each element are in the
compound.
For example, H2O

11. • Hydrogen Gas H2 • Oxygen Gas O2
•Let's start with a couple of Molecules

12. • Methane CH4
• Silicon Dioxide SiO2
• Ammonia NH3
• Propane C3H8
•Now for some compounds

14. •What is the difference between a compound and a
molecule?
• A molecule is formed when two or more atoms join
together chemically.
• A compound is a molecule that contains at least two
different types of atoms.
• All compounds are molecules but not all molecules are
compounds.
