Explanation:
Detailed explanation-1: -Atomic number is the number of protons or electrons in an atom. Since this is countable, it’s always a whole number.
Detailed explanation-2: -Atomic Number is simply the total number of protons/ electrons present in an atom. We are counting whole objects here. Hence the atomic number is always a whole number.
Detailed explanation-3: -The atomic masses of most elements are fractional because they exist as a mixture of isotopes of different masses.
Detailed explanation-4: -The reason the atomic mass is not a whole number is because it’s the weighted average mass of the isotopes of that specific element.
