3. Describe the structure of an atom and learn about the methods and discoveries of Rutherford.

C9. Trends and Patterns 1. Recognize Groups and Periods 2. Consider the similarities in the elements of a Group eg. Group 1, Group 7 and Group 8 3. Consider the chemical trends within a Group 4. Relate atomic structure to Periods 5. Recognize the unique position of hydrogen 6. Order properties of metals and non-metals for comparison. 7. State the properties of metals and say in what ways some are exceptional.

C10. Reactivity Series 1. explain how metals and non-metals react with oxygen, water and acid 2. Compare the rates of reaction of some metals with oxygen. 3. Compare the rates of reaction of some metals with water. 4. Compare the rates of reaction of some metals with dilute acid. 5. Construct a reactivity series for metals. 6. Know the methods of extraction of some metals and some non-metals. 7. explain why the historical order of the discovery of metals is related to their reactivity 8. make predictions about displacement reactions 9. Give examples of displacement reactions. There are different types of chemical changes: 1) Synthesis: Elements are chemically combined to make compounds. eg. a. carbon + oxygen -> carbon dioxide b. magnesium + oxygen -> magnesium oxide c. Iron (Fe) + sulfur (S) -> iron sulfide (FeS)

2) Displacement An atom or group of atoms is replaced by another atom. eg. hydrochloric acid + magnesium -> magnesium chloride + Hydrogen : The magnesium atom has taken the place of the hydrogen atom

3) Decomposition reactions Compounds are broken down into simpler substances. Bacteria produce enzymes that speed up decomposition. Heat and electricity can also decompose compounds. eg. copper carbonate (CuCO3 and heat) -> CuO + CO2

= Class activity: Reactions of metals and their compounds =

Find best youtube video clip(s) that explain 4 types of chemical reactions. Describe why the video clip(s) of your choice is the best explanation(s) and save the link(s) in Word then, submit it on MB by the end of the class.

The videoclip should: 1. define four types of chemical reactions. 2. include a sample equation for each type of chemical reaction. 3. not play longer than 10 minutes.

C11. Chemical equations and Preparation of Salts 1. Explain how to prepare some common salts by the reactions of metals and metal carbonates and be able to write word equations for these reactions. 2. state the preparation of copper sulphate. calcium chloride. zinc chloride or zinc sulphate crystals.

Complete a balanced word equation using the chemical equation of combustion of methane below. Image from [|www.middleschoolchemistry.com] 2. Hydro carbon or any C, H, O compound 3. Produces carbon dioxide and water 4. Produces heat (Exothermic reaction) and light energy 5. Examples: i). methane combustion: complete combustion/ produce CO2 and H2O ii). candle burning: incomplete combustion/ products CO, C, Soot, CO2, H2O iii). most of alcohol is flammable produce blue flame which is complete combustion of the fuel iiii). combustion of hydrogen: 2H2 + O2 >> 2H2O || 1. Metal or nonmetal reacts with oxygen 2. Produces an oxide of the element 3. Produces heat (Exothermic reaction) 4. Examples: i). C + O2 >> CO2 ii). 2Ca + O2 >> 2CaO iii). 4Na + O2 >> 2Na2O iiii). 4Fe +3O2 >> 2FeO3 x). S + O2 >> SO2 || [|Combustion vs oxidation] from www.differencebetween.com [|Combustion vs oxidation] from www.differencebetween.net
 * In the reaction, the the bonds in the methane and oxygen come apart, the atoms rearrange and then re-bond to form water and carbon dioxide.
 * The little number written at the lower right after an atom (subscript) tells how many of that atom are in the molecule.
 * The big number written in front of a molecule (coefficient) shows how many of that molecule there are.
 * All the atoms in the products come from the atoms in the reactants.
 * Combustion (Burning) || Oxidation ||
 * 1. Fuel reacts with oxygen
