››More information on molar mass and molecular weight. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. Radium-226 (atomic mass = 226.025402 amu) decays to radon-224 (a radioactive gas) with a half-life of 1.6 *10^3 years. What volume of radon gas (at 298 K and 1 atm pressure) is produced by 24.0 g of radium in 4.5 days?

• Ra-226 is readily assimilated by the body (f1 = 0.2) • Rn-222 is a noble gas. The Radium atom Ra has an Atomic Number of 88 an Atomic Mass of 226 and a from CHEMISTRY 12 at Seton Home Study School Radium (Ra) Atomic Number = 88 Mass = 226.0 g mol -1 Electron Configuration = [Rn]7s 2 Density = 5.5 g cm-3. Radium was first discovered in 1898 by Marie Sklodowska-Curie, and her husband, Pierre Curie, in a pitchblende uranium ore in North Bohemia in the Czech Republic; however, it was not isolated as a pure metal until 1902. 226Ra 88 60Co 27 nucleus of Cobalt-60 with 27 protons and 33 neutrons nucleus of Cesium-137 with 55 protons and 82 neutrons nucleus of Radium-226 with 88 protons and 138 neutrons AX Z Chemical symbol for the element Atomic mass number = Z+N Atomic number or X-A (Co-60) (Cs-137) (Ra-226) प्रतिक- Ra: Atomic mass- 226: 89: नाम- Actinium “Periodic Table Atomic Mass of Elements in hindi” के इस लेख को Mass numbers of typical isotopes of Radium are 226.
