Elements |
There are 91 naturally occurring elements, and another 25 that are created artificially. The atoms of an element are specific to that element, having a particular number of protons, neutrons, and electrons. Most elements combine with others to form compounds, such as water (hydrogen and oxygen). It's the many combinations of elements that make for the variety of substances in the world. Keeping track of all the elements would be difficult were it not for the handy periodic table, which organises the elements by atomic structure. Hydrogen, the simplest of elements, always exists as a compound. Hydrogen fuels both stars and the rockets that reach for them. The light bulb is a study in practical elements. Because tungsten has the highest melting point of any metal, it makes the perfect material for the filaments that, once electrified, glow with white-hot light. Inside the bulb's glass is not oxygen but argon, used because it won't react with the tungsten filament. Carbon is the stuff of diamonds and the stuff of life. The process by which diamonds are created and extracted is slow and arduous. It's no wonder the flashy gems are so valued. In a fireworks display, the elements are showcased. From the propellants to the colours to the patterns, a fireworks show is a chemical extravaganza. |

| Title: |
Voltage and Voltaic Cells |
Explains and defines electrical measurements. Voltages are measured from laboratory and Daniell cells. Discusses reasons for a standard half-cell potential and explains the electric potentials on the Reduction Half-Reaction Table. The reduction table is then used to predict net voltage values for redox reactions and to determine if the reaction is spontaneous or non-spontaneous. Students are challenged to design a cell with a specific voltage. |

| Title: |
Writing and Predicting Equilibrium for Bronsted-Lowry Equations |
Prediction of Bronsted-Lowry acid-base neutralisations is based on acid-base strength determined from an acid-base data table. Reactions involving polyprotic acids and anions of polyprotic acids can be predicted by adding the proton transfer equations together. Students test and evaluate these predictions through laboratory activities. |
