2. Objective

2. Building Blocks of Matter
The fundamental building blocks of matter are atoms and molecules.
These particles make up elements and compounds.

3. Atoms and Elements
An atom is the smallest unit of an element that maintains the chemical identity of that element.
An element is a pure substance that cannot be broken down into simpler, stable substances and is made of one type of atom.

4. The Periodic Table
Elements are arranged vertically into groups that share common chemical properties.

5. The Periodic Table
Elements are also organized horizontally into rows, or periods.

6. Alkali Metals
The elements on the left side of the table (Groups 1 and 2) are reactive metals
The elements of group 1 are known as the alkali metals.

7. Alkaline-earth Metals
The elements of Group 2 are called alkaline-earth metals.
Alkaline-earth metals are also too reactive to be found in nature as pure elements.

8. Transition Elements Transition elements are metals
They are good conductors of electricity
Unreactive
Ex: Gold

9. Halogens.
Halogens are the most reactive nonmetals.

10. Noble Gases
Unreactive

11. Metalloids Metalloids: B, Si, Ge, Ar, Sb, Te
Properties between metals and nonmetals

12. Your Assignment Color and Label the periodic table:
Alkali Metals (pink/red)
Alkaline Earth Metals (orange)
Transition Elements (yellow)
Metalloids (green)
Halogens (blue)
Noble Gases (purple)
