A substance that is made from atoms of two or more elements that are chemically bonded (H20)
|
|
|
What is a molecule?
|
The smallest unit of an element or coupound that retains all the properties of that element or compound
|
|
|
What can properties help determine?
|
The identity of an unknown substance, but comparisons of several properties must be made

|
|
|
What is a physical property?
|
A characteristic that can be observed or measured without changing the identity of the substance
|
|
|
What do physical properties describe?
|
The subject ittself, not what it can change into.
