Elaborate on how the isotopes and their relative abundances affect the average atomic mass of an element. a. average atomic mass comes from the mass of the isotope nucleus and is proportioned by the relative abundances. b. the different masses of isotope electrons gives the relative abundance and average atomic mass of the isotopes. c. isotope mass both varies in neutron numbers and is weighted by its relative abundance to give the average atomic mass. d. when calculating the average atomic mass of the element, the number of protons gives the relative abundance of the isotopes.
