What are the building blocks of matter
- 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
- 9. Let’s Build Some Molecules And Compounds! This activity is for illustration only
- 10. Element Element Symbol Color of Gummy Hydrogen H yellow Carbon C green Oxygen O blue Silicon Si black Nitrogen N red
- 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.
- 16. •Mixtures • Most matter in the universe is found in mixtures. • A mixture is made from two or more substances either elements, compounds or both - that are not chemically combined. • Soil is a mixture • The atmosphere is a mixture of gases

- 21. •Solutions • A solution is a mixture in which one substance dissolves in another. • For example salt water. • A solute is the substance that dissolve. • A solvent is the liquid it dissolves in
- 22. • Solution When you add salt to water The salt will completely dissolve. In this example : The solute is salt The solvent is water
- 23. Which of the following is a solution?
