The layout of the table has been refined and extended over time,as new elements have been discovered, and new theretical models have been developed to explain chemical behaviour. The current standard table contains 117 confirmed elements as of late 2006 ( while element 118 has been synthesised, element 117 has not ). This table is displayed on this t - shirt.
