Polonium ( IPA: /pə(ʊ)ˈləʊniəm/) is a chemical element in the periodic table that has the symbol Po and atomic number 84. A rare radioactive metalloid,
Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass.

Two samples, each containing an estimated 10 curies (2 mg) of polonium-210, were purified by vacuum distillation and evaporated onto oblique sections of x-ray targets made of copper. Four lines of the K series and ten lines of the L series of the x-ray spectrum of polonium were recorded with a one-meter transmission crystal spectrograph and a 25-centimeter Bragg spectrograph, respectively

The atom is therefore changed from polonium to lead. equation: 4) Marie Sklodowska Curie discovered the radioactive element polonium in 1898 . Its chemical symbol is Po, and its atomic number is 84. Several isotopes were properties it was impossible to decide with this information alone whether polonium was a metal or a non-metal. Its atomic number of 84 places it in Group VI-B Atomic Number: 84. Atomic Weight: 209. Melting Point: 527 K (254°C or 489°F).
