1. Periodic Table Basics

2. 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?

3. 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.

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

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

6. 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.

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

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

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

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

How can you differentiate between periods and groups?

13. Think Pair Share - Write
How can you differentiate between periods and groups?
Answer: Periods go across and groups go down.

14. Think Pair Share - Write
How are elements grouped on the periodic table?

15. Think Pair Share - Write
How are elements grouped on the periodic table?
Answer: Elements are grouped according to their similarities.

16. Think Pair Share - Write
What happens to the atomic number as you move across or down the periodic table?

17. Think Pair Share - Write
What happens to the atomic number as you move across or down the periodic table?
Answer: The atomic number increases as you move across and down the periodic table.

18. Think Pair Share - Write
What happens to the atomic mass as you move across or down the periodic table?

19. Think Pair Share - Write
What happens to the atomic mass as you move across or down the periodic table?
Answer: The atomic mass increases as you move across or down the periodic table.

20. Think Pair Share - Write
How do you know the number of valence electrons for each element?

21. Think Pair Share - Write
How do you know the number of valence electrons for each element?
Answer: The number of valence electrons is determined by the group number.

22. How Did You Do?
Thumbs Up!
I GOT IT!
Thumbs Down!
I’M STILL CONFUSED

23. 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.

24. Coloring the Periodic Table
As we move through the groups on the periodic table,
Color code it on your copy.
Write the information in the chart.

25. ALKALI METALS Group 1 Hydrogen is not a member, it is a non-metal
1 electron in the outer shell
Soft and silvery metals
Very reactive, esp. with water
Conduct electricity
Image:

26. ALKALINE EARTH METALS Group 2 2 electrons in the outer shell
White and malleable
Reactive, but less than Alkali metals
Conduct electricity

27. TRANSITION METALS Good conductors of heat and electricity.
Groups in the middle
Good conductors of heat and electricity.
The transition metals are able to put up to 32 electrons in their second to last shell.
Can bond with many elements in a variety of shapes.

28. Noble Gases Group 18 Exist as gases Non-metals
8 electrons in the outer shell = Full
Helium (He) has only 2 electrons in the outer shell = Full
Not reactive with other elements

29. Rare Earth Metals Located at the Bottom Some are Radioactive
The rare earths are silver, silvery-white, or gray metals.
Conduct electricity

31. Think Pair Share - Write
What happens to the reactivity of the elements as you move from left to right across the periodic table?

32. Think Pair Share - Write
What happens to the reactivity of the elements as you move from left to right across the periodic table?
Answer: The reactivity of the elements decreases as you move from left to right.

33. Think Pair Share - Write
Which group wants nothing to do with the other elements? Why?

34. Think Pair Share - Write
Which group wants nothing to do with the other elements? Why?
Answer: The Noble Gases will not bond with other elements because they already have a full outer energy level (8 valence electrons).

36. Metals, Nonmetals, & Metalloids
Conduct electricity
Shiny
Makes up ¾ of the periodic table

37. Metals, Nonmetals, & Metalloids
does not conduct electricity
found on the right side of the periodic table

38. Metals, Nonmetals, & Metalloids
Properties of metals & nonmetals
