The periodic table is a table of the chemical elements in which the
elements are arranged by order of atomic number in such a way that the
periodic properties (chemical periodicity) of the elements are made
clear. The standard form of the table includes periods (usually
horizontal in the periodic table) and groups (usually vertical).
Beautiful flash widgets for blog and website. Elements in groups have
some similar properties to each other. There is no one single or best
structure for the periodic table but by whatever consensus there is, the
form used here is very useful. The periodic table is a masterpiece of
organised chemical information. The evolution of chemistry's periodic
table into the current form is an astonishing achievement with major
contributions from many famous chemists and other eminent scientists.
