❖ Atom-the smallest unit of an element that maintains the chemical properties of that
element

sugar), NaHCO2 (soluble salt)
➢ II. Properties and Changes in Matter
❖ Physical Property-a characteristic that can be observed that does not involve changing
the identity of the substance
● Examples: color, shape, mass, volume, viscosity
❖ Physical Change-a change of matter from one form to another without a change in
chemical properties
● Examples: tearing, cutting, melting, boiling
❖ Change of State- the change of a substance from one physical state to another
❖ Chemical Property-a property of matter that describes a substance’s ability to transform
into different substances
