Did You Know...?
The periodic table of the chemical elements is a tabular method of displaying the elements, which was first devised in 1863. The layout of the table has been refined and extended over time, as new elements have been discovered, and new theoretical models have been developed to explain chemical behaviours. The current standard table contains 117 confirmed elements as of late 2006.
