Question
Mny elements have non-integral atomic masses because :
Options
A.they have isotopes
B.their isotopes have non-integral masses
C.their isotopes have different masses
D.the constituents, neutrons, protons and electrons, combine to given fractional masses
Solution
Average atomic of an element is given by = 
Ai = atomic mass of isotope
Xi = % abundance of isotope
Ai = atomic mass of isotope
Xi = % abundance of isotope
