Answer:
It has the most quantitative effect on the average atomic mass of the element.
Step-by-step explanation:
Tungsten's most common isotope will have the most quantitative effect on the average atomic mass.
The most common isotope of tungsten will represent its most abundant isotope.
- The proportion by which each element occurs in nature is the geonormal abundance.
- The geonormal abundance is used to calculate the average atomic mass.
The isotope with the most geonormal abundance will have the highest effect on the average atomic mass of an element.
