1. How are elements organized on the Periodic Table?
S8P1e. Develop models (e.g., atomic-level models, including drawings, and computer representations) by analyzing patterns within the periodic table that illustrate the structure, composition, and characteristics of atoms (proton, neutrons, electrons) and simple molecules.
Instructional Approach(s): The teacher should introduce the essential question and the standard that aligns to the essential question

2. What is the Periodic Table?
It represents our understanding of the structure and usefulness of the atoms that have been identified in our environment
Elements are organized on the Periodic Table based on similar properties
Instructional Approach(s): The teacher should present the information on the slide while the students record important information on their notes
Picture from

3. The Periodic Table contains over 100 different Elements
Instructional Approach(s): The teacher should present the information on the slide

4. What do the numbers and Letters mean?
Element Name
Atomic Number (# protons and electrons in its atom)
Element’s Chemical Symbol
Instructional Approach(s): The teacher should present the animated slide while the students record the important information on their notes. With each click of the mouse, the following information is shown: element name, atomic number (with definition), chemical symbol, and atomic mass (with definition)
Atomic Mass (p + n)

5. The Atomic Number Increases
What do you notice about the Atomic Number of Elements as you move Left to Right and Up to Down on the Periodic Table of Elements?
The Atomic Number Increases
Instructional Approach(s): The teacher should pose the question to the class. The teacher can call on students or ask for volunteers to answer the question. When ready, the teacher can click the mouse to show the answer

6. So how is the Periodic Table arranged?
The Periodic Table is organized like a big grid.
The properties of an element can be predicted from its location in the Periodic Table
There are rows (left to right) and columns (up and down). Each row and column mean something different.
Instructional Approach(s): The teacher should present the animated slide while the students record the important information on their notes.

7. The Periodic Table can also be divided into three main types of Elements: Metals, Metalloids, and Nonmetals
Instructional Approach(s): The teacher should present the animated slide while the students record the important information on their notes.

8. Metals Metals are shiny Metals are solid at room temperature
Metals have high conductivity
Metals can be flattened and not shatter (malleable)
Instructional Approach(s): The teacher should present the animated slide while the students record the important information on their notes.

9. Nonmetals Nonmetals are not shiny
Nonmetals are mostly gaseous at room temperature
Nonmetals are poor conductors
Nonmetals are brittle and will shatter easily (not malleable or ductile)
Instructional Approach(s): The teacher should present the animated slide while the students record the important information on their notes.

10. Metalloids
Metalloids have characteristics between metals and nonmetals
Metalloids are solid at room temperature
Metals are semi-conductors
Instructional Approach(s): The teacher should present the animated slide while the students record the important information on their notes.

11. Periods Each horizontal row of the table is called a period
Each row represents the number of energy levels present in an atom of the element
Instructional Approach(s): The teacher should present the slide while the students record the important information on their notes.

12. Groups (Families) The Columns are called Groups There are 18 groups
The Elements in a group have the same number of electrons in their outer energy level
Groups are often “grouped” together to form Families because of similar properties
Instructional Approach(s): The teacher should present the slide while the students record the important information on their notes.

13. Groups (Families)
You probably know a family with several members who look a lot alike. The Elements in a group or family in the periodic table often-but not always-have similar properties.
Instructional Approach(s): The teacher should present the slide while the students record the important information on their notes.

14. use this for #12 on notes
Instructional Approach(s): The teacher should present the animated slide while the students record the important information on their notes.

16. Groups (Families)
Although you are not expected to know the names of the similar “family (groups)”, here is a quick glance. [Names vary depending on source]
Instructional Approach(s): The teacher should present the slide introducing the next few slides. Once again, the students do not have to know the actual names of each family (group). Just introduce the information to them.

17. Hydrogen
The properties of Hydrogen do not match the properties of any single group, so it is set apart. It is above Group 1 because it has 1 electron in its outer energy level like Group 1.

18. Alkali Metals

19. Alkaline-Earth Metals

20. Transition Metals

21. Boron Group

22. Carbon Group

23. Nitrogen Group

24. Oxygen Group

25. Halogen Group

26. Noble Gases

27. Rare Earth Elements

28. Periodic Table and States of Matter
Most Periodic Table models also indicate whether an element is a solid, liquid, or gas.
Instructional Approach(s): The teacher should present the slide while the students record the important information on their notes.

29. Let’s Review the Basics of the Periodic Table
Instructional Approach(s): The teacher should show the video to reinforce the Periodic Table

30. Reactivity of Elements
Atoms will often take, give, or share electrons with other atoms in order to have a complete set of electrons in their outer energy level. Elements whose atoms undergo such processes are called Reactive and can combine to form compounds. Since “Groups” [columns] are similar because they have the same number of electrons in their outer energy level, the Periodic Table is also organized by degree of reactivity.
Instructional Approach(s): The teacher should present the slide while the students record the important information on their notes.

31. Reactivity of Elements
In general, Elements located on the left of the Periodic Table are most reactive metals, least reactive metals in the middle, and least/ nonreactive on the right.
Instructional Approach(s): The teacher should present the slide while the students record the important information on their notes.

32. Reactivity of Elements (#16 on notes)
