Average Atomic Mass

Question 1

Isotopes

Answer 1

Atoms of the same element that differ in mass (different number of neutrons)

Question 2

Average Atomic Mass

Answer 2

The mass shown on the periodic table is weighted, average mass of all the isotopes present in a naturally occurring sample of that elements

Question 3

Average Atomic Mass Equation

Answer 3

AAM=E(Fractional Abundance X Isotopic Mass)
