Answer: The mass of the atom is basically the average atomic mass of all the stable isotopes.
Explanation:
Average atomic mass is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
For Example: Taking the element silicon
Three isotopes of Silicon, which are Si-28, Si-29 and Si-30.
Average atomic mass of silicon = 28.086 amu
As, the average atomic mass of silicon is closer to the mass of Si-28 isotope. This means that the relative abundance of this isotope is the highest as compared to the other two isotopes.
Percentage abundance of Si-28 isotope = 92.2%
Percentage abundance of Si-29 isotope = 4.7 %
Percentage abundance of Si-30 isotope = 3.1%
Hence, the mass of the atom is basically the average atomic mass of all the stable isotopes.
