Ra 226

Radium is a chemical element with the symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. Pure radium is silvery-white, but it readily reacts with nitrogen (rather than oxygen) upon exposure to air, forming a black surface layer of radium nitride (Ra3N2). All isotopes of radium are radioactive, the most stable isotope … TīmeklisO rádio (do latim científico radium, irradiar) [ 1] é um elemento químico de símbolo Ra, número atômico 88 (88 prótons e 88 elétrons) com massa atómica [226] u, …

Tīmeklis226 and radium-228. Radium-226 has a long half-life (1,600 years) compared to that of radium-228 (5.75 years). A half-life is the time required for half of the initial amount of the radionuclide to decay. Radium-226 decays by emitting the nucleus of a helium atom (alpha particle), whereas radium-228 emits an electron (beta particle). hompimpa gamersTīmeklis2016. gada 6. maijs · One gram of Ra-226 has an activity of 1 Ci (not exactly, but close enough for our purposes) and Ra-226 has a half-life of 1600 years.
