The atomic number is derived from how many protons are present in the nucleus of an atom. Becaue you cannot have a fraction of a proton present in an atom, atomic numbers must be non negative integers.

∙ 15y agoAtomic numbers are whole numbers because they represent the number of protons in an atom's nucleus, which is a fundamental property of an element. Protons have a positive charge, and each element has a unique number of protons. Consequently, atomic numbers are always listed as whole numbers in the Periodic Table to reflect this inherent characteristic.

∙ 15y agobecause you cant split a proton in half. you have it or you dont. You dont have 3 and a third protons

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.
Few elements have isotopes. their atomic mass is not a whole number.
Atomic numbers represent the number of protons in an atom's nucleus, which are always whole numbers because protons are indivisible particles. Atomic numbers cannot be fractions or decimal numbers because they refer to a count of discrete, whole particles.
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.

There is no element with the atomic number 3.14. Atomic numbers are whole numbers that represent the number of protons in an atom's nucleus.

Because relitive atomic masses are NEVER whole numbers.

The atomic number is the number of protons.
WHICH numbers? The most prominent one is probably the average atomic mass, but it might be the atomic number.
1. All the atomic numbers are whole numbers. 2. If you think to atomic weight of heavy radioactive elements (atomic numbers from 93 to 118) is a rule of IUPAC to indicate in square parenthesis, [], the atomic mass of the most stable or known isotope.

Because the masses of protons, neutrons and electrons are not whole numbers.
because of its no. in table of elements
Because it is an average of the masses of the isotopes of the element, each of which has a different atomic mass (not mess!)
