Why is the atomic mass of an element not a whole number while the atomic number is?

The atomic number refers to the number of protons in the atom. Since the proton cannot be an in-between number, the atomic number will have to be a whole number.
On the other hand, the Atomic Mass does not have to be a whole number because it is the mass of an atom and is roughly equivalent to the number of protons plus the average number of neutrons in that particular element.

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 element has an atomic mass of 32.06?
Sulfur- Element Number 16 on the Periodic Table of Elements
What would cause the average atomic mass to be close to a whole number?
The average atomic mass of an element would be closer to a whole number if there were few to no electrons. This means having little to no electrons in the element's isotopes.
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.
The mass number of an element is equal to what of an element?
The sum of the number of protons and the number of nuetrons.
What element has the atomic number for 3.14?
No element has this atomic number. All atomic numbers are whole numbers.
What do whole numbers on the periodic table represent?
The whole number, the one at the top, above the element's symbol in the element box, is the atomic number. The atomic number is the number of protons per atom in that particular element. The bottom number, that is always a decimal, is the atomic mass.
Is the atomic mass of an element is always a whole number of atomic mass untis?
No.
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.
How do you calculate average atomic number of an element?
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.
Which number in an element box on the periodic table is the atomic number?
The atomic number is the whole number indicating the number of protons. It is usually directly above or below the element symbol.
Why at atomic number not whole number in most case?
The question is based on an ignorance of what an atomic number is. It represents the number of protons in an atom of the element and is always, ALWAYS a whole number.
How do you figure the number of neutron's in an atom?
Take the Atomic Mass and round it to the nearest whole number. Then subtract this number and the atomic number of that element.
How do you get the number of protons electrons and neutrons from the atomic mass number and atomic number?
Number of protons = atomic number Number of neutrons = Atomic Mass (rounded to the nearest whole number) minus the atomic number Number of electrons in a stable element = number of protons Number of electrons in an unstable element = atomic number minus the charge
What element has an atomic mass of 32.06?
Sulfur- Element Number 16 on the Periodic Table of Elements

The average atomic mass of an element would be closer to a whole number if there were few to no electrons. This means having little to no electrons in the element's isotopes.
