1. S8P1f. Recognize that there are more than 100 elements and same have similar properties as shown on the Periodic Table of Elements.

2. The Periodic Table  This week we will be learning about the periodic table. S8P1f.  EQ: What is the Periodic Table of Elements?  Answer EQ: (skip three lines)  Go ahead and cut the pictures you have been handed on the dashed lines. Page 41 - 43

3. Learning Goals  LG1: I will know and understand the periodic table, how to find an element, and be able to list similar properties of some elements.  LG2 : I will know and understand the periodic table, find elements, list similar properties of most elements, and understand that they have different atoms.  LG3 : I will know and understand the periodic table, find elements, list similar properties of most elements, while connecting it to previous knowledge of matter and atoms.

4. Family Talk  Talk with your family group: What is the Periodic Table of Elements? How is the table organized? VL2 You have two minutes!!!

5. Table Talk: Sort the pictures below into three groups. VL 2

6. Now, organize each group by one characteristic. (ex. size, color, or shape) VL 2

7. YellowBlueWhite No Edges Most Edges

8. SeasonalChocolateGummy Hard Candy Bulk January December Chewy Crunchy No sour Sour Less Fruity More Fruity Wrapped Unwrapped

9. Table of Candy 1. Take a group at a time and sort by one characteristic. Examples: Chewy to Crunchy, Fruity to Less Fruity ***When you are done sorting, I will give you directions to glue

10. Reflection Question:  Is there a time in your life that you felt like you had to organize something like the periodic table? (closet, room, bathroom)

11.  Periodic Table – table where elements are organized by increasing atomic number. The periodic table is arranged by groups and periods. P. 41 - 43

12.  Groups – vertical columns of elements with similar properties. groups are numbered 1-18 Elements in same group have the same number of electrons in their outer energy level.

13.  Periods – horizontal rows of elements that contain increasing numbers of protons and electrons. Periods are numbered 1-7 Each row in the periodic table ends when an outer energy level is filled

14. Each element on the periodic table has this information:  Element Symbol  Element Name  Atomic Number  Atomic Mass Atomic mass Draw this! Make sure you add color!

15.  Element Symbol – a symbol that has either 1 or 2 letters to help identify elements  Atomic number – the number of protons in an atom  Atomic mass – composed mostly of protons and neutrons in the nucleus AKA mass number

16. Metals, Nonmetals, and Metalloids EQ: Where are the metals and nonmetals located on the periodic table? EQ Answer: (skip three lines) P. 44 - 45

17.  Metals – good conductors of heat and electricity, all but Mercury are solid at room temperature. Metals are located to the left of stair step

18.  Alkali Metals – (Group 1) are the most reactive of all metals; don’t occur in nature in their element form.

19.  Alkaline Earth Metals – (group 2) shiny, ductile and malleable; combine readily with other elements. Ductile: made into long wire Malleable: made into shapes

20.  Transition Elements – (groups 3-12) most familiar metals because they often occur in nature uncombined.  Inner Transition Metals – (listed below table) Lanthanide Series – elements with atomic number 58-71 Actinide Series – elements with atomic number 90-103

21.  Nonmetals – elements that are usually gases or brittle solids at room temperature; located to the right of the stair step  Noble Gases – (group 18) exist as isolated atoms. They are all stable because outer energy level is filled.

22.  Metalloids – elements that make up stair step; have metallic and non-metallic properties Metalloids are part of the mixed groups – which contain metals, non-metals and metalloids.

23. Uus

24. Foldable EQ: What is the difference between a group and a period on the periodic table? EQ Answer: (Skip a two lines)  Come in quietly so we can start a video. ***Keep in mind you will be doing this in front of your class next week!! https://www.youtube.com/watch?v=v1TfPDlA 1xE P. 48

25. Foldable  On the pink paper, follow directions with me to know how to fold your paper.

26. Alkali Metals (Outside) Most Reactive!!!!! Bad kids on the table Don’t occur in nature in element form Sodium is in table salt Draw one of these

27. Alkaline Earth Metals  Metallic/shiny  Easily made into shapes and wire  calcium is in our bones to make them strong and our milk

28. Metalloids  Divide the table between metals and nonmetals.  Mixed Group  On the flap: Arsenic is poison, usually In rat poisoning

29. Noble Gases  Stable  On the flap: Makes signs that light up In different colors

30. Post it note  Do you feel confident over the different groups on the periodic table? Write on the sticky note your answer:  Yes, then explain what helped them understand better  Almost, what they are struggling with  No, what can the teacher do to help

31. Masses of Atom EQ: What is atomic mass? EQ Answer: (skip three lines) Label the parts to this element! P. 49-50 8 O Oxygen 15.999

32. Atomic mass – composed mostly of protons and neutrons in the nucleus AKA mass number **** Remember that electrons are super small they barely have a mass! Page 49

33.  Atomic number – the number of protons in an atom; number of protons also identifies the element. If you need to find the # of neutrons of an atom: Mass # – Atomic # = # of Neutrons

34.  Isotopes – atoms of the same element that have different number of neutrons Different isotopes have different properties

40. Independent Work!!!  You will be handed a worksheet. You will need to calculate the number of protons, neutrons, and electrons in an atom.  If you need help, raise your hand! VL: 0 Atomic # = Protons Electrons Atomic Mass – Atomic # = Neutrons

41. Post it note  Do you feel confident over finding the number of protons, neutrons, and electrons? Write on the sticky note your answer:  Yes, then explain what helped them understand better  Almost, what they are struggling with  No, what can the teacher do to help

42. Using the Periodic Table  Fill out the below box for this element: P. 52 SymbolAtomic #Atomic Mass NeutronProtonElectron

43.  To find the # of protons  Look at atomic number P. 52 # of Protons

44.  To find the # of electrons  Look at atomic number P. 52 # of Electrons

66. Discuss in your group about the picture below…. VL: 2

67.  Each element has a certain number of electrons. To find the number of electrons we use Atomic Number.  There is a certain number of electrons that we can place in different electron shells.

68.  Each of the seven energy levels can hold a maximum number of electrons. Level 1: 2 electrons Level 2: 8 electrons Outer level can hold a max of 8 electrons Except hydrogen and Helium (Only max of 2) The Noble Gases (group 18) are stable because their outer shell is full.

69. Uus
