Atomic Mass is not a whole number

Atomic Mass is not a whole number. because it takes into account all the isotopes of an element. To calculate, multiply the % abundance of each isotope by the relative mass of each and add together. 3.1. (7.42% x 6.015) + (92.58% x 7.016). 100. Natural lithium is: 7.42% 6 Li (6.015 amu)
