Question

Explain why atomic masses of many elementa are in fractions and not whole numbers.​

Answer 1

Answer:

Most elements occur as a mixture of isotopes of different masses. The fractional atomic masses arise because of this mixture.

The atomic masses of most elements are fractional because they exist as a mixture of isotopes of different masses. Most elements occur as a mixture of isotopes of different masses.

Answer 2

Answer:

atomic masses

Explanation:

atomic mass of most of the element in atomic mass units involve fractions because atomic mass of an element is the average of relative masses of the various isotopes while taking average, the results appears as fractions .
