Hi,\nHydrogen is the lightest of all elements. Its chemical symbol is H and it is Diatomic (Not monoatomic, as gruffalo said). Hydrogen has 3 isotopes, Protium, Deuterium and Tritium. An isotope of an element is an element with the same atomic number, but different atomic mass. The atomic number of Hydrgen molecule is 2, but the different atomic masses of the 3 isotopes are... Protium = roughly 1, Deuterium = roughly 2 and Tritium = roughly 3. Hydrogen is placed at the top of the 1st group in the periodic table, with all the alkali metals, however, Hydrogen exhibits characteristics of both metals and non-metals and is considered as non-metallic. Properties of metals exhibited by Hydrogen is that it reacts with the Halogens. Like HCl or HBr... Properties of non-metals exhibited by Hydrogen is that it reacts with reactive metals like Sodium or Pottasium. Like, NaH or KH... \nThats all I can think of at the present...
