After five weeks of term studying atoms and elements, molecules and compounds, the periodic table and the carbon cycle, we are ready for our first test. Make sure you revise all of Chapter 2 thoroughly and complete the “Summing Up” section at the end of the chapter. You will be required to memorise the first twenty elements of the periodic table (names and symbols), which will be worth 20 points. This will be of great assistance for science in future years. You can use the mnemonic “Little Betty Boron Chews Nitrogen On Friday Nights” and “NaMgAl SiPS Chlorine Ardently” to help you remember most of the first twenty.
You will also need to know the three different forms of Carbon – as shown above, Diamond, Graphite and Charcoal.
