For chemists, knowing an element's position in the periodic table, and the company it keeps, is still the most reliable indicator of its properties – and a precious guide in the search for new substances. "It rivals Darwin's Origin of Species in terms of the impact of bringing order out of chaos," says Peter Edwards of the University of Oxford.

The origins of the periodic table lie in the 19th century, when chemists noticed that patterns began to emerge among the known chemical elements when they... click here to continue:
