Element Infographics – Group 7

This graphic looks at the halogens, found in Group 7 of the Periodic Table. This group consists of the elements fluorine, chlorine, bromine, iodine and astatine – the as yet unnamed artificial element 117, ununpentium, may also be a halogen. As always, the following are a few interesting nuggets of information too long to fit […]

Element Infographics – Group 6

This latest graphic looks at the elements of Group 6. Unlike with Groups 3, 4 where ‘Crystallogens’ and ‘Icosagens’ are alternative names that are not officially recognised by IUPAC, ‘Chalcogens’ is an IUPAC accepted name for Group 6. Go figure. The ‘ch’ is pronounced as a hard c, like the ‘ch’ in ‘chemistry’, whilst the […]

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 […]

The Chemistry of Fireworks

The colours in fireworks stem from a wide variety of metal compounds – particularly metal salts. ‘Salt’ as a word conjures up images of the normal table salt you probably use every day; whilst this is one type of salt (sodium chloride), in chemistry ‘salt’ refers to any compound that contains metal and non-metal atoms ionically […]

Element Infographics – Group 4

This latest infographic focuses on the Group 4 (Group 14 in IUPAC nomenclature) elements. 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 […]

Element Infographics – Group 3

┬áThe latest in the series of infographics on groups in the periodic table, this one looks at some general information on Group 3. I’m aware that, technically (according to IUPAC) it should be referred to as Group 13; however, since these infographics are intended to be used in a secondary school classroom, and the majority […]
