Holding elements together: Ionic bonds
February 19th, 2012 |

A while ago, I wrote a couple of posts describing some intra-molecular forces, forces that hold atoms and molecules together. I enjoyed writing them, and people come back to read them quite frequently, so I thought I’d continue and write about a couple more. The previous posts covered van der Waals forces and hydrogen bonds (and dipoles!) [...]

Holding molecules together – van der Waals forces
A while back, I did a post for Chemistry week about hydrogen bonds. In it, I mentioned why I find intramolecular forces so fascinating; they are interactions on such a tiny scale that hold together everything from small molecules like water to massive molecules like the enzymes and multi-enzyme complexes that I study. The hydrogen-bond [...]

Water is everywhere on our planet. In the air, in our bodies, in our food and in our breath. Without it life as we know it would not be possible. Water is vital for the survival of all living things, yet as a molecule it has some pretty odd behaviour. Water molecules stick to each [...]
