L'hydrogène est l'élément chimique de numéro atomique 1, de symbole H. L'hydrogène présent sur Terre est presque entièrement constitué de l'isotope 1H (un proton, zéro neutron) ; il comporte environ 0,01 % de 2H (un proton, un neutron). Ces deux isotopes sont stables. Un troisième isotope 3H (un proton, deux neutrons), instable, est produit dans les explosions nucléaires. Ces trois isotopes sont respectivement appelés « protium », « deutérium » et « tritium ».
The periodic table, also known as the periodic table of elements, arranges the chemical elements such as hydrogen, silicon, iron, and uranium according to their recurring properties. The number of each element corresponds to the number of protons in its nucleus.
The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. The columns, called groups, contain elements with similar chemical behaviours. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are the halogens; and group 18 are the noble gases. Also displayed are four simple rectangular areas or blocks associated with the filling of different atomic orbitals.
Russian chemist Dmitri Mendeleev published the first recognizable periodic table in 1869, developed mainly to illustrate periodic trends of the then-known elements. He also predicted some properties of unidentified elements that were expected to fill gaps within the table. Most of his forecasts soon proved to be correct, culminating with the discovery of gallium and germanium in 1875 and 1886 respectively, which corroborated his predictions.
Mendeleev's idea has been slowly expanded and refined with the discovery or synthesis of further new elements and the development of new theoretical models to explain chemical behaviour.
