Back to some chemistry basics for today’s post, with a look at the nine different hazard symbols commonly used to warn of chemical dangers. These symbols are frequently encountered in the lab – and also on some household products – and whilst some are self-explanatory, others can require a little more in the way of explanation, which is what this graphic aims to do.

Glassware in the laboratory comes in a range of different shapes and sizes, and is used for a number of purposes. Don’t know your round-bottomed flask from your Florence flask, or your pipettes from your burettes? This graphic has you covered. Below there’s also a little detail on the usage of each.

VSEPR & Shapes of Molecules

November 13th, 2014|

One for the chemistry students (and teachers!) out there today, with a look at how we can work out the shapes of some simple molecules using Valence Shell Electron Pair Repulsion (VSEPR) theory. These shapes are decided by the arrangement of electrons around the central atom in the molecule.

Mole Day – Avogadro & The Mole

October 23rd, 2014|

Today, 23rd October, is Mole Day – which might put you in mind of small, furry, burrowing animals. However, they don’t even seem to have a commemorative day of any kind; we’re actually talking about the mole in chemistry, a quantity that essentially allows us to ‘count’ atoms and molecules in a more convenient way. This is a fundamental concept, and one that all chemists utilise.

The Compound Interest Periodic Table of Data

Today’s graphic is one that I’ve been working on over the past couple of weeks. Every chemistry classroom has a Periodic Table, but it’s often a drab affair; considering it’s one of the cornerstones of chemistry, I thought I’d attempt to produce a more dynamic looking version. The result is the above table – each element is shown within a circle that contains a variety of data pertaining to that element.

Periodicity: Trends in the Periodic Table

February 12th, 2014|

This graphic looks at several properties of elements in the Periodic Table. These properties show trends, also referred to as ‘periodicity’, as you progress along a period. The emphasis of this graphic is on giving a general impression of each of the trends; although a rough scale is given to the right of each diagram, this is intended to be for approximate reference, rather than allowing the diagrams to be used as precise tools for determining properties of specific elements. Each diagram is also accompanied by a brief explanation of the trends, and a simple explanation of basic anomalies.
