2. ATOMS Atom: basic building block of matter.
An atom is the smallest particle of an element that has the properties of that element.

3. ELEMENTS: Elements are arranged in columns or groups.
Elements in any one group have similar chemical properties.

4. Protons are Important!
Different arrangements of protons may result in different forms of an element.

5. COMPOUNDS
A compound is made up of two or more elements that are chemically combined.

6. Classification of the Periodic Table:
Scientists classify elements based on their properties.
Three Basic Kinds of Elements found on the Periodic Table:
Metals are good conductors of electricity, shiny, and heat well.
Non-metals are poor conductors of heat and electricity, dull luster.
Semi-metals have properties between metals and non-metals (heat better than non-metals, but poorer than metals).

7. Classification of the Periodic Table:
Scientists also classify elements according to their state of matter (gas, solid, liquid).
The majority of the elements on the Periodic Table are solids (only 2 are liquids & 11 are gases).

8. Broken up by Solids, Liquids, & Gases
Br (Bromine) & Hg (Mercury) are the only Liquid Elements at room temperature.

9. Broken up by Metals, Non-Metals, & Semi-Metals (Metalloids):

10. MATTER
Matter: is everything that takes up space and has mass.

11. MATTER
The three forms of matter are: Solid, Liquid, and Gas. There is a 4th state of matter (plasma), but we will just be talking about the 3 states of matter in this class.

13. States of Matter:

15. Solids:
A solid keeps its shape and has a certain volume.

16. Liquids: A liquid doesn’t have a certain shape of its own.
A liquid takes the shape of its container.

17. Gases:
A gas doesn’t have a certain shape or a certain volume.

18. Closure Questions What is matter? What are the three states of matter?
Does a solid keep it’s shape?
Does a solid have a certain volume?
Does a liquid keep it’s shape?
Does a gas keep it’s shape?
Does a gas have a certain volume?
