The abundance of radium in the sea waters is 8,9.10-14 mg/L.
The atomic number of radium is 88 distributed such that:First energy level 2Second energy level 8Third energy level 18Fourth energy level 32Fifth energy level 18Sixth energy level 8seventh energy level 2Accordingly, radium loses two electrons on ionization to be a positive ion.
Yes it is a grade level.
