Isotope practice worksheet with answers.

Relative atomic mass. The relative atomic mass ( Ar) of an element is the average mass of the naturally occurring atoms of the element. This quantity takes into account the percentage abundance of all the isotopes of an element which exist. Given that the percentage abundance of is 75% and that of is 25%, calculate the A r of chlorine.Isotope name atomic # mass # # of protons # of neutrons # of electrons Potassium-37 Oxygen-17 uranium-235 uranium-238 boron-10 boron-11 Isotopes .
