Exploring the Periodic Table S8P1e. Develop models by analyzing patterns within the periodic table that illustrate structure, composition and characteristics of atoms. Instructional Approach(s): The teacher should introduce the essential question and the standard that aligns to the essential question

Copy This! WU 10//17 Periodic Table Activating Strategy List three ways you would organize, DVD movie selection and why we organize? Alphabetical order Genre/ subject Date/Main Actor/years It helps us find it quicker and it gives us information about that DVD. Instructional Approach(s): The teacher should make a seating chart before the class period. If you already have a seating chart, create a different one using another organization method. Possible organizational ideas for the arrangement include placing students by birth date, by height, or alphabetically by their first names. Create a blank seating chart template that can be used by the students to fill in the student information they gather. Or, use the table on the student section of the Placement Pattern Activity sheet [linked on the matter resource page]. The teacher should facilitate the activity while the students follow the direction on the Placement Pattern sheet to complete the activity. The teacher should discuss the analysis questions with the class.

Exploring The Periodic Table 1. List three things you already know about the periodic table. 2. Discuss/list four things you notice about the Periodic Table and its organization and the information on the periodic table.

Exploring The Periodic Table 3.List three questions you would like to ask about the periodic table. Leave 2 lines between each question. 4. Discuss your questions with your group and come up with a group list of three questions. Write on the colored paper.

Copy This! WU10/4 What do the numbers and letters mean? Element Name Atomic Number: The number of protons. Defines the element Atomic Number 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 Atomic Mass: The mass of one atom of the element

Exploring the periodic table 1. As you move left to right up and down The atomic number and atomic mass increases. 2. One way the periodic table is organized is by structure- the number of protons, neutrons and electrons in every element.

Copy This! WU10/4 Exploring the Periodic Table. Atomic number= number of protons = number of electrons 2. Atomic mass = number of protons + number of neutrons. 3. Isotope = Atoms with the same atomic number but different numbers of neutrons.

Practice Questions

Practice Questions Assignment: Finish the rest of the worksheet and turn it in to your teacher.

What is the Periodic Table? 1. It represents our understanding of the structure and usefulness of the atoms that have been identified in our environment 2. 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 www.chem4kids.com

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

What do the numbers and Letters mean? Instructional Approach(s): Transition slide leading to the answers on the next slide

The Atomic Mass/Atomic Number Increases 5. 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 Mass/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

So how is the Periodic Table arranged? 6. The Periodic Table is organized like a big grid. 7. The properties of an element can be predicted from its location in the Periodic Table Instructional Approach(s): The teacher should present the animated slide while the students record the important information on their notes.

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

Text Book Fact Finding You Do! Finish off work from yesterday! Using Text book Pages 118,129,135 Summarize 9. 4 physical and chemical properties of all metals 10. 4 properties of all non-metals 11. 3 properties of all metalloids

9. 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.

10. 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.

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

Exploring the Periodic Table . Periods 12. Each horizontal row of the table is called a period 13. There are 7 rows 14. 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.

Groups (Families) 15. The Columns are called Groups. 16. There are 18 groups 17. The Elements in a group have the same number of electrons in their outer energy level (Valence Electrons) Instructional Approach(s): The teacher should present the slide while the students record the important information on their notes.

Groups (Families) What properties or characteristics do you share with your family? 18. Elements in groups are together because they often share similar properties. They belong to that family. 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.

Complete #18 on your Notes Instructional Approach(s): The teacher should present the slide while the students record the important information on their notes.

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.

Reactivity of Elements 19. In general, Elements located on the left of the Periodic Table are most reactive metals, least reactive metals in the middle, and nonmetals on the right. Instructional Approach(s): The teacher should present the slide while the students record the important information on their notes.

Reactivity of Elements Instructional Approach(s): The teacher should present the slide while the students record the important information on their notes.

Let’s Review the Basics of the Periodic Table http://studyjams.scholastic.com/studyjams/jams/science/matter/periodic-table.htm Instructional Approach(s): The teacher should show the video to reinforce the Periodic Table

Complete Your Periodic Table *Gas **Liquid Instructional Approach(s): The students should complete their notes while the teacher walks around and checks student work.

3-2-1 Summarizing Strategy Name at least 3 ways the Periodic Table is organized. Identify the 2 numbers given for each element. Identify the main purpose of the Periodic Table. Instructional Approach(s): Each student should complete the summarizer. The teacher should use the summarizer to determine the level of student mastery and if differentiation is needed.
