1. Reviewing sc.8.P.8.5

2. Atomic Structure

3. Knowing Atomic Structure
Name the 3 particles that make up an atom.
What are the charges of each particle?
Where would you find each particle?

4. What is the periodic table?
A chart of the elements arranged into rows and columns according to their physical and chemical properties.
It can be used to determine the relationships among the elements.

5. Reading the Periodic Table
Periods – go across
Groups – go down

6. How do you read the periodic table?
Mass
Mas

7. What is the atomic number?
The number of protons found in the nucleus of an atom Or
The number of electrons surrounding the nucleus of an atom.

8. What is the chemical symbol?
An abbreviation of the element name.

9. What is the atomic mass?
The number of protons and neutrons in the nucleus of an atom.

10. What is the atomic number?
What is the atomic mass?
How many protons?
How many electrons?
How many neutrons?

11. What is the atomic number?
What is the atomic mass?
How many protons?
How many electrons?
How many neutrons?

12. Metals, Nonmetals, & Metalloids
Which ones are the metals?
Which ones are the nonmetals?
Which ones are the metalloids?

13. What do we know about elements in the same group?

14. How can you determine the number of valence electrons?
Valence electrons are the number of electrons in the outer energy level.
The last # of the group # = valence electrons

15. Find the number of valence electrons for the following:

16. Groups to Remember Group 1 = Alkali Metals
Group 2 = Alkaline Earth Metals
Group 17 = Halogens
Group 18 = Noble Gases

17. Elements, Compounds, & Mixtures

18. Homogeneous vs. Heterogeneous Mixtures
Homogeneous is the same throughout.
Heterogeneous is not the same throughout.

20. Is it an element, compound, or mixture?

21. Acids & Bases

22. Learning Scale
Level 4 – Investigate and describe the compounds formed by bonding elements. Level 3 – Describe how elements combine to form compounds. Describe the motion of the particles in a solid, liquid, and gas. Level 2 – Use the periodic table to identify the number of protons, neutrons, or electrons in an element. Level 1 – Locate and identify elements on the periodic table.
