Atomic Mass of Radium Atomic mass of Radium is 226 u.
2020-11-21 by Nick Connor Atomic Mass of Radium Atomic mass of Radium is 226 u.
The unit of measure for mass is the atomic mass unit (amu). ›› Ra molecular weight. Molar mass of Ra = 226 g/mol. Convert grams Ra to moles or moles Ra to grams ›› Percent composition by element Radium (88 Ra) has no stable or nearly stable isotopes, and thus a standard atomic weight cannot be given. The longest lived, and most common, isotope of radium is 226 Ra with a half-life of 1600 years. 226 Ra occurs in the decay chain of 238 U (often referred to as the radium series).
