The question is based on a complete lack of understanding as to what the atomic number is! They are always, without exception, whole numbers.
There are two numbers that are included in every element's block on every periodic table. The whole number, which can range from 1 - 118 is the atomic number of that element. The atomic number is the number of protons in the nuclei of the atoms of that element. The second number is the atomic weight and is never a whole number, except for the artificially prepared elements, and then it is a whole number written inside parentheses.There may be other numbers listed as well, depending on the periodic table. All periodic tables have a key as to what everything inside each block represents.
The atomic number is the whole # on the periodic table or the # of protons in an atom. The atomic mass is the # that is not the whole # on the periodic table, or you can multiply the mass of the isotope by its abundance and add the answers together.
Few elements have isotopes. their atomic mass is not a whole number.
Elements exist as isotopes in nature. So their atomic weight is not a whole number.
The modern periodic law states that, The properties of the elements are the periodic function of there atomic number not atomic weights.
Why are atomic masses of elements not generally whole numbers? The atomic masses listed on the periodic table are a weighted AVERAGE of an element'sisotopes. ... An element's atomic number is the number of protons in its nucleus. Number of protons specifies atom type.
There is no average atomic number. The atomic number of an element is the number of protons in the nuclei of its atoms. It is a whole and finite number. The elements are arranged in order of increasing atomic number on the periodic table.

Tungsten (W) has an atomic number of 74. This number is high compared to the whole Periodic Table. There are only 18 more natural elements with a higher number.
The atomic number is the whole number indicating the number of protons. It is usually directly above or below the element symbol.
Because relitive atomic masses are NEVER whole numbers.
The atomic mass given on the periodic table is a weighted average of all the isotopes, weighted by abundance of each isotope
