Key to the Periodic Table  Elements are organized on the table according to their atomic number, usually found near the top of the square. Hydrogen is found in significant abundance in undetected form of mass, such as dark matter, and in gas giant planets and stars. Hydrogen has electron configuration of 1 s 1.To become stable it can either accept to get helium configuration that is a stable configuration or it can even donate one electron.Hence it is very confusing where to place either in the metals group as it donates or in nonmetal group as it accepts an electron. * Dihydrogen *It resembles both alkali metals and halogens and therefore, its position is anomalous.
