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.

Why the atomic mass numbers listed for elements on the Periodic Table are not whole numbers.?
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.
What is an element's atomic mass not listed as a whole number on the periodic table?
Few elements have isotopes. their atomic mass is not a whole number.
What number is the whole number found in the periodic table?
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.
Why are atomic numbers always whole numbers?
An atom can't contain only part of a proton, so the number must always be a whole number
The atomic mass of the elements are not whole value numbers because of the existence of?
D. Protons

What element has the atomic number for 3.14?
No element has this atomic number. All atomic numbers are whole numbers.
What is an element's atomic mass not listed as a whole number on the periodic table?
Few elements have isotopes. their atomic mass is not a whole number.
Why is the relative atomic mass of chloride not a whole number?
Because relitive atomic masses are NEVER whole numbers.
Why are all atomic numbers whole numbers?
The atomic number is the number of protons.
What do the numbers listed for an element on the periodic table represent?
WHICH numbers? The most prominent one is probably the average atomic mass, but it might be the atomic number.

Why are the elements 94 through 110 in the periodic table whole numbers?
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.
Why don27t elements in the periodic table have whole numbers for their atomic masses?
Because the masses of protons, neutrons and electrons are not whole numbers.
How are the elements on a periodic table listed?
by the number of atomic numbers in the element and the amount of mass numbers in the element. these are the numbers on the top and bottom of each element.eg. Helium (Symbol He) has a mass number of : 4 and an atomic number of:2
Why aren't atomic masses of elements not whole numbers?
because of its no. in table of elements
Why is an element's atomic mess not listed as a whole number on the periodic?
Because it is an average of the masses of the isotopes of the element, each of which has a different atomic mass (not mess!)
