The structure of a small molecule can also be shown as a three-dimensional ball-and-stick model. These models show how the atoms and bonds are arranged in space. The diagram shows a ball-and-stick ...

This model explains the properties of substances ... Small molecules - AQA A covalent bond is a shared pair of electrons. Covalent bonding forms molecules. Substances with small molecules have ...

When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...

The ability to record compositional and bonding maps in two dimensions will enable studies of microscopic inhomogeneities that may underlie the symmetry-breaking and spatial variations in ...

A small piece of sodium metal is placed in a flask of chlorine gas. A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic ...
