Hello Jonny,

I have a question for you.

In the internet I have found values for the mass of certain elements - and the mass of specific isotopes. What I want to know is why are some mass values integer while others not. For example we have 272Rg with 272.1535, and 279Rg with 279. Is it because scientists cannot compute the binding energy so they cannot come up with a reliable exact value?

If so can we make a educated guess? Using the data I have been able to gather I have computed the average atomic weight of all 118 elements. But given the fact that some values are integer - and probably not the real - actual values, is there a way to estimate this average with and then without the binding energy? Something tells me it is not that simple as the equation you posted for Don - I mean for all cases. Thanks in advance.

BR Ogygos
