1 Name: Group Member Names: 1. Shade the location of the chemical families on the following period table of elements. a. Alkali metals (Light) b. Alkaline earth metals (Dark) c. Noble gases (Dotted) d. Halogens (Diagonal Line) 2. How are elements arranged in the periodic table in general? The atomic number of elements increases / decreases (circle one) as you go left to right. The atomic number of elements increases / decreases (circle one) as you go down. 3. What is similar about elements in the same family? Elements in the same family have common chemical and physical properties because they have the same number of electrons. 4. In order to achieve the stable arrangement of noble gas atom, each alkali metal atom would have to lose / gain (circle one) electron. As a result, it forms atom / element / isotope / ion (circle one) with +1 charge. 5. In order to achieve the stable arrangement of noble gas atom, each halogen atom would have to electron. As a result, it forms with - 1 charge. 6. In a neutral atom, the number of proton / neutron / electron (circle one) is always equal to the number of proton / neutron / electron (circle one) or the atomic number. 1

2 7. Isotopes of an element are two different forms that have the same number of proton / neutron / electron (circle one) and proton / neutron / electron (circle one), but with different numbers of proton / neutron / electron (circle one). 8. Give the total number of electrons in each shell for the following neutral elements: Element Total # of First shell Second shell Third shell Fourth shell electrons Aluminum 2 None Nitrogen None None Calcium 8 Lithium Argon 8 9. Draw the Bohr diagram of neon and explain why noble gases are unreactive. 10. Draw the Bohr diagram for Mg 2+ and S 2-. Do not forget the square brackets! 11. Write the chemical name or formula for each of the compounds below: (Hint: Binary compounds have name ending ide. The number of atom in covalent compound is represented by using prefix like mono, di, tri If the metal is multivalent, use the Roman numeral like I, II, III in a bracket like (II) to indicate the charge.) BeF 2 FeCl 2 CaO Mg 3 P 2 KOH SO 2 Na 2 CO 3 PCl 5 P 4 S 10 Fe 2 O 3 MnO 2 potassium sulfide iron (III) bromide magnesium nitrate 2

3 dinitrogen tetroxide tin (IV) sulfide lithium sulfate diphosphorus pentoxide aluminum bromide lead (II) phosphate 16. State the law of conservation of mass. The total number of is equal to the total number of the in a chemical reaction. 17. What particles are conserved in a chemical reaction? 18. Use COEFFICIENTS to balance the following chemical equations. If the equation is already balanced, state that next to the equation. SO 2 (g) + O 2(g) à SO 3(g) Fe 2 O 3(s) + H 2(g) à Fe (s) + H 2 O (l) P 4(g) + O 2(g) à P 4 O 10(g) Al (s) + CuSO 4 (aq) à Al 2 (SO 4 ) 3 (aq) + Cu (s) C 2 H 6 (g) + O 2 (g) à CO 2(g) + H 2 O (l) 19. What do the following subscripts mean? (g) (l) (s) (aq) 20. Identify each chemical reaction as synthesis, decomposition, single- replacement, double- replacement, neutralization or combustion reaction. Al 2 (SO 4 ) 3 + 3Ca(OH) 2 à 2Al(OH) 3 + 3CaSO 4 2C 2 H 2 + 5O 2 à 4CO 2 + 2H 2 O Mg + 2AgNO 3 à Mg(NO 3 ) 2 + 2Ag 2PbO 2 à 2PbO + O 2 2Be + O 2 à 2BeO H 2 SO 4 + Ca(OH) 2 à CaSO 4 + 2H 2 O 3

Complete the following reactions by predicting the products and balance the reactions when necessary: Mg (s) + O 2(g) à NaCl (aq) à AgNO 3(aq) + Cu (s) à FeF 3(aq) + CuBr (aq) à HCl (aq) + NaOH (aq) à C 4 H 10(g) + O 2(g) à 22. Classify the following as acidic, basic, or neutral. Apples Bleach Black coffee Lemon juice Soap Kitchen cleaner Coke Water 23. Classify the following substances as acids, bases, salts, or organic compounds: KCl is NaOH is Ca(OH) 2 is C 4 H 10 is HBr is C 2 H 6 O is H 2 SO 4 is NaNO 3 is 24.

6 Safety Look at the laboratory setting and point out as many safety issues as possible. Paste the setting on to the poster and circle each issue. The more the better! Go for a scavenger hunt: o Fire extinguisher o Lab coats and safety goggles o Fire blanket o Fire alarm o Emergency shower o Eyewash station o Broken glass bucket o Fume hood o Dust pan and broom o Door closest to the bathroom Draw a rough top view sketch of the classroom and highlight it with the items above. Present the scenario and summarize how the safety issue can be improved. Also present where each item is in the classroom. Periodic Table Trend Complete Q1-5 and ensure the answer is uniform within the group. If unsure, ask Ms. Yajima! Draw a rough periodic table on the poster. Present the summary of: o How atomic number and atomic mass behave within the table. o How family (group) and period are defined. o How to determine # of valence electrons for an element. o What the common charges are. o Whether the element is likely to gain or lose electrons and why. o Where metals, non- metal, and metalloids are found. o Where seven diatomic elements are found. Bohr Diagram Rules Complete Q6-10 and ensure the answer is uniform within the group. If unsure, ask Ms. Yajima! Using words and diagrams, write the summary of the rules of drawing Bohr diagram for neutral element, positive ion, and negative ion on the poster. Giving examples would be helpful. Present the summary of the rules first. Then show an example with a mistake to ask if the class can spot the mistake. 6

7 Naming Complete Q11 and ensure the answer is uniform within the group. If unsure, ask Ms. Yajima! On the poster, using words and diagrams, write how to interchange chemical name and chemical formula for: o Ionic compound o Covalent compound Present the summary first. Then show an example of each of the following: o Ionic compound made of a metal with only one charge o Ionic compound made of a multivalent metal o Ionic compound made of a polyatomic ion o Covalent compound that begins with di o Covalent compound that begins without prefix Chemical Reaction Complete Q18-20 and ensure the answer is uniform within the group. If unsure, ask Ms. Yajima! On the poster, using mainly drawing, summarize six types of chemical reactions. Then write how to predict products if chemical formula of reactants are given. Also on the poster, create a summary of four states. Solid, liquid, aqueous, and gas. Make a cartoon drawing for each state and emphasize the difference between them. Present the types of reactions and give an example of how to predicting products for each type. Mention four states in the discussion. Type of Compounds Complete Q21-22 and ensure the answer is uniform within the group. If unsure, ask Ms. Yajima! On the poster, create a tree diagram/concept map to include all of the following. Include lots of examples of each. o Ionic compound Acids Base Salt o Covalent compound Organic compound Also on the poster, draw a ph scale. Underneath of the scale, draw objects that are associated with the ph value. Present the tree diagram and ph scale to the class. 7
