Matter Properties and Changes

Page 2: Chapter 3 Matter Properties and Changes. Atom: The smallest particle of an element that retains all the properties of that element –Comprised of protons,

• Atom: The smallest particle of an element that retains all the properties of that element– Comprised of protons, neutrons and electrons

• Element: A pure substance that can’t be broken down by physical or chemical means.– An atom of any element always has the same

number of protons.

Properties and Changes

• Substance: Matter that has a uniform unchanging composition– Also known as a pure substance– Ex: water, only composed of two different

substances, and can not be separated by physical means.

• Mixture: Two or more substances combined having variable composition– Ex: salt water, contains two substances, and

can be separated by physical means.

Types of Substances

• Compounds– Can be separated by

chemical means– Composed of two or

more different elements in distinct whole number ratios

– Ex: Water, H2O– Ex: Salt, NaCl

• Elements– Elements can not be

separated by chemical means

– Ex: Gold, Au– Carbon, C

Types of Mixtures

• Homogeneous– A mixture with no

physically distinct parts in the solution.

– Ex: Salt water– Ex: air

• Heterogeneous– A mixture with distinct

physical boundaries.– Ex: granite– Ex: orange juice

Changes

• Physical Change: Change that does not alter the chemical composition of the substance.– Ex: Melting ice

• Chemical Change: One or more substances are changed into other substances– Ex: chemical reaction

Physical Properties

• Properties that do not involve or describe a substance changing into another substance

• Or, a characteristic that can be observed or measured without changing the sample’s composition.

• Ex: Melting Point, Boiling Point, Hardness, and Luster

Physical Properties

• Extensive Properties: Depends on the mass of a substance– Ex: Mass, Length, Volume

• Intensive Properties: Does not depend on the amount of the substance present– Ex: Density, Solubility

Chemical Properties

• The ability of a substance to combine with or change into one or more other substances. – Ex: Iron reacts readily with the oxygen in the

air to form iron oxide (rust).
