WebThe atomic weight of a given specimen of elementary substance no longer necessarily gives certain evidence as to the atomic weight of a specimen of fundamentally different origin. But on the other hand, the several values of the atomic weights are not only characteristic of the specimens concerned, but also give us perhaps the most certain clue ... WebComment Two: only the mass numbers may be given if this element is adenine made-up single. For example: "ChemTeam-42 and ChemTeamium-44 exist. Calculate the abundant if the atomic weight is 42.68." Since ChemTeamium doesn't exist, you can't view up exact isotopic weights. So, use 42 and 44 in the solution to the problem.
