In this slide show we will explain

• Elements• Compounds• Heterogeneous and Homogeneous

mixtures• Physical and Chemical Properties • Physical and Chemical Changes

Page 3: Matter And It’s Changes

Elements

• Elements are forms of matter on the Earth that have a specific location on the Periodic Table of Elements

• Elements can be solids, liquids, and gasses

• Elements can either be natural occurring or man made

• Elements are placed on the Periodic Table shown behind this slide

Page 4: Matter And It’s Changes

Compounds • A compound is a substance containing two or more

different elements bonded together into a fixed mass ratio

• Compounds are different from mixtures because a mixture can be made by only mechanical means, Compounds must be formed by chemical reactions

• All compounds can exist as solids, liquids, and gases • Compounds are named differently then elements here is

a link to a site that shows you how to name them • http://www.woodrow.org/teachers/chemistry/links/

Heterogeneous and Homogeneous mixtures

• There are two types of Mixtures and they are Heterogeneous and Homogeneous

• A heterogeneous mixture is a mixture where there is a change in it’s state of matter

• A homogeneous mixture is a mixture where it remains uniform throughout the entire mixture

Physical and Chemical Properties

• Physical properties are properties that do not change the chemical nature of the matter

• Some examples are freezing point, color, smell, melting point, and so on

• Chemical Properties are properties that will change the chemical nature of the matter

• Some examples are heat of combustion, reactivity with water, and electromotive force

Physical and Chemical Changes

• A physical change is where the change dose not change the chemical make up of the structure

• A major example is the change from solid to liquid to water to steam

• A chemical change is where the chemical make up of the substance is changed and energy is either absorbed or given off

• Some examples are burring, oxidation, and photosynthesis
