Atoms are the building blocks of everything. Atoms can form strong bonds with each other, making molecules. Symbols and formulae Letters from the alphabet are used to represent chemical elements.

A chemical element is one of those squares on the periodic table that adorns many a classroom wall. Sure. But what is an element really? It is a more subtle question that you might realise.

His principal contribution to chemistry was the 'vis tellurique' (telluric screw), a three-dimensional arrangement of the elements constituting an early form of the periodic classification, published ...

The periodic table arranges all chemical elements in special ways. Different types of chemical bonding, and patterns and trends can be observed in their arrangement. Structure and bonding Elements ...
