(A) Elements have non-integral atomic masses because they exist as a mixture of isotopes with different masses,which occur in nature in specific proportions. For example,Chlorine $(Cl)$ has two isotopes with mass numbers $35$ and $37$,present in a ratio of $3:1$. Therefore,the average atomic mass is calculated as: $\frac{3 \times 35 + 1 \times 37}{4} = 35.5 \ u$. Thus,the presence of isotopes with different masses leads to non-integral atomic masses.
