Mass defect and binding energy need 90 positive charges and so we need an atomic number here of 90 so the identity of the other product just look at up here

Radium (Ra) är ett grundämne i det periodiska systemet med atomnummer 88 och protoner (samma atomnummer), men olika antal neutroner (olika masstal). är ett av de radioaktiva grundämnen som bildas när radium-226 sönderfaller.

An atom of radium with atomic mass 226 and atomic number 88, `Ra^226_88` , decays to an atom of Radon with atomic number 86.

Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance.

›› 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.
