Why Chilli Peppers are Spicy: The Chemistry of a Chilli

The idea for this graphic came to me whilst saving the chilli peppers from a forlorn looking, aphid-infested chilli plant that’s probably on its metaphorical last legs. I thought it would be quite interesting to look at the origin of the heat in chilli peppers, and how this can be quantified.

Element Infographics – The Lanthanides

This graphic looks at the elements known as the lanthanides – the ones stranded at the bottom of the periodic table, along with the actinides. For a group of elements that doesn’t really get much attention in chemistry teaching until at least undergraduate level, their applications are remarkably widespread and varied. Most modern electronic devices […]

Element Infographics – Transition Metals

This graphic looks at some general properties of the transition metals – I had a little less space to work with than with the previous graphics, on account of the large number of elements that the transition metals encompass, but hopefully what’s included is still of use.

Element Infographics – Group 8

Getting towards the end of this particular series of infographics now – whilst this graphic completes the overview of specific groups, there are still graphics on the transition metals, lanthanides and actinides to come. The noble gases are one of the better known groups of elements in the Periodic Table, and whilst some of their […]

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 […]
