Atomic number =(( % textAbundance ) ×( text Isotope )1+ % text of text (Isotope) 2/100)

Q. Atomic mass of an element is not necessarily a whole number because

It contains electrons, protons, and neutrons

It exists in allotropic forms

It contains isotopes

Atoms are no longer indivisible

Atomic number
$= \frac{( % Abundance ) \times ( Isotope ) _{1} + % of (Isotope) _{2}}{100}$

Atomic number =100(%Abundance )×( Isotope )1​+% of (Isotope) 2​​

Atomic number
$= \frac{( % Abundance ) \times ( Isotope ) _{1} + % of (Isotope) _{2}}{100}$
