Element Infographics – Group 5

The latest of the element infographics looks at the Group 5 elements. They are referred to more commonly as the Nitrogen Group rather than the Pnictogens, although this more archaic name seems to find more use than the archaic names of Groups 3 & 4. There is, once again, an interesting fact that I couldn’t […]

Again, the name ‘crystallogens’ is technically not recognised by IUPAC – nor is ‘tetragens’, the other archaic name – but ‘the carbon group’ just doesn’t have the same ring to it. One extra fact to add for the curious: although tin […]

Christmas Cracker Chemistry

Chances are you’ll be making use of christmas crackers over the holiday period. Chances also are that you’ve never really given a lot of thought to the chemical compounds contained therein, or the chemical reaction that makes christmas crackers go bang. Well, allow me to elaborate. Christmas crackers owe their crack to a compound called […]

Element Infographics – Group 2

The second of a series of infographics on the groups of the periodic table, here some general properties of the group 2 elements are examined. As stated previously, these are primarily aimed at secondary school students, hence the relative simplicity and generality of the information presented. If you want to download this infographic for your […]
