All things are made up of atoms. There are 92

different types of atoms, called elements.

Page 3: Chemical & physical properties - Davis School · PDF fileExamples of chemical properties are... Paper burns Iron (Fe) rusts CO 2 doesn’t burn Silver (Ag) doesn’t react w/water

Each element has different

properties.

Page 4: Chemical & physical properties - Davis School · PDF fileExamples of chemical properties are... Paper burns Iron (Fe) rusts CO 2 doesn’t burn Silver (Ag) doesn’t react w/water

The properties of matter can be grouped

into two categories: physical and

chemical properties.

Boiling Pt/Melting Pt

• This is NOT burning!

• Not all things melt or boil!!

• Does wood melt?

• Most biotic (living or once-

living) things DO NOT melt!

Chemical properties...1. Definition– Can only be observed as it

changes to a different type of matter.

(Changes to a new molecule.)

The ability to change into something new.

How it reacts with others.

2. Chemical Properties to memorize:

1. Flammability

2. Rustability

3. Reacts with water

4. Reacts with acid

Page 19: Chemical & physical properties - Davis School · PDF fileExamples of chemical properties are... Paper burns Iron (Fe) rusts CO 2 doesn’t burn Silver (Ag) doesn’t react w/water

3. Examples of chemical properties are...

Lets Review…Physical Properties: properties we can

measure without changing the identity of

the matter.

Chemical Properties: a substance’s ability

to change into something new. It can only

be observed while the change is taking

place.

(We use these properties to distinguish

chemicals from one another)
