in case of some elements which has isotopes the atomic masses are different so the average is taken out which may come in decimals.

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.
What element has an atomic mass of 32.06?
Sulfur- Element Number 16 on the Periodic Table of Elements
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 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 is the weighted average mass of all the know isotopes for an element?
It is its Atomic Mass and why atomic mass is frequently not a whole number.
What is the mass of an element?
The mass number of an element is the atomic mass rounded to the nearest whole number. For Example, if the atomic mass is 54.94 (Manganese [Mn]), then the mass number will be 55. You can use the mass number to calculate the amount of neutrons in an isotope.
What is the difference between the atomic number and the atomic mass?
Atomic mass is the mass of 1 mole of the element. Atomic number is the number of protons the element has
Can explain in terms of isotopes why the relative atomic mass of atomic number 17 is not a whole number?
Mass number is the average of all the naturally occurring isotopes of that element. When calculated, this average is not a whole number.
What is the atomic number and the mass number of an element with 20 atomic number and 23 mass number?
Sodium is a metal element. Atomic mass number of it is 23.
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
