Answer:
Explanation:
The average atomic mass for any element will be closest to the average atomic mass of the __different______ isotopes.
To calculate the average atomic mass of any element, the mass spectrometry method helps to determine the proportion/percentage/fraction by which each of the isotopes of an element occurs in nature. The proportion is called the geonormal abundance or abundance. From this, the average atomic mass of an element from different isotopes can be calculated.
