STUDENT LEARNING OBJECTIVES SPI 9.1 Recognize that all matter consists of atoms SPI Use the periodic table to determine the properties of an element. TOC: #56. Periodic Table #57. Element Cards CW: Check Study Guide for chapters Battleship with the Periodic Table Test tomorrow!!!

Check Study Guide 1.Name the three parts of an atom and where they are located. a. Protons- inside Nucleus b. Neutrons- inside Nucleus c. Electrons- outside Nucleus in the Electron Cloud 2.What charge does each part of the atom have? a. Protons...Positive + b. Neutrons...No charge (Neutral) c.Electrons...Negative – 3. What part of the atom is responsible for an atom’s ability to bond with other elements? Electrons 3.What part of the atom is responsible for an atoms identity? Protons 4.How do you know the number of protons an atom has? Atomic Number 5. How do you know the number of electrons an atom has? The # of electrons = the number of protons (Atomic Number) 6.How many electrons are in each energy level/shell? –1st level/shell - 2 –2nd level/shell - 8 –3rd level/shell- 18

7. What is the atomic mass? The mass of an atom; the # protons + # of neutrons 8. What parts of the atom account for the atomic mass? protons & neutrons 9. What is an isotope? An atom that has the same number of protons but a different number of neutrons 10. Are isotopes always the same element? Why? Yes, the # of protons determines an atom’s identity and it does not change with an isotope of that element. 11.Define periodic. Repeated in a regular pattern or interval 12. What is the periodic table? An aid used to describe and show properties of the known elements 13.What are the three categories on the periodic table? a. Metals b. Metalloids c. Nonmetals

14. How is the periodic table organized? into periods(rows) and groups(columns) based on the atomic number 15. What is the name of each group? a. Group 1 Alkali Metals B. Group 2 Alkaline Earth Metals c. Group 3-12 Transition Metals d. Group 13 Boron Group e. Group 14 Carbon Group f. Group 15 Nitrogen Group g. Group 16 Oxygen Group h. Group 17 Halogens i. Group 18 Noble Gases 16.How many electrons in the outer level/shell? a. Group 1 – 1 electron b. Group 2 – 2 electrons c. Group 13 – 3 electrons d. Group 14 – 4 electrons e. Group 15 – 5 electrons f. Group 16 – 6 electrons g. Group 17 – 7 electrons h. Group 18 – 8 electrons 17. What does the # of electrons in the outer energy level indicate about the element? It’s ability to form chemical bonds with other elements; it’s chemical reactivity

Periodic Table Battleship Materials: two different color dry erase markers Two periodic table battleship boards dry eraser or paper towel Objective: is a game for two players where you try to guess the location of five ships your opponent has hidden on a grid. Players take turns calling out a row and group (column name on periodic table), attempting to name an element containing enemy ships. Procedure: Each player takes a marker and a periodic table board and props it open so that the other player can not see it. Using the marker, mark ships on the lower part of the board. Each player marks four ships either vertical or horizontal (no diagonal). Ship’s lengths are: 2 ship, 3 ship, 4 ship, and 5 ship.After each player has marked their ships’ placement, trade markers with the other person so no one is tempted to switch positions of ships. Player with the birthday closest to the current date goes first. On your turn, call out an element symbol and atomic number(for higher level you can call out the group/family name such as noble gasses or alkali metals)from the periodic table. Your opponent checks that space on their lower periodic table, reads the name of the element square, and says "miss" if there are no ships there, or "hit" if you guessed a space that contained a ship. Mark your shots on your upper periodic table, with dots for misses and X for hits, to keep track of your guesses. When one of your ships is hit, put an X on that ship on your lower periodic table at the location of the hit. Whenever one of your ships has every slot X’d, you must announce to your opponent that he has sunk your ship. Victory: The first player to sink all opposing ships wins. Clean Up: completely erase all marks on boards, cap markers and leave station neat
