do you mean the why is the average Atomic Mass not a whole number? because if that is your question, then the answer is that each element has multipal isotopes and the mass you see on the Periodic Table is the average of all the isotopes together. So there has to be a decimal on the periodic table of elements

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.
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.
To determine the empirical formula of a compound, you need the molar masses of its elements and their ratio in the compound. Calculate the ratio of the elements in terms of whole numbers, which will give you the empirical formula.
Elements with atomic numbers 89-94: natural elements.Elements with atomic numbers 95-98: artificial elements but they are also discoverd in nature as ultratraces.Elements with atomic numbers 99-103: artificial elements.
because of its no. in table of elements
Elements also possess isotopes. So their average atomic mass is rarely whole number.
Because the masses of protons, neutrons and electrons are not whole numbers.
I dont know does that help u
The atomic masses of most elements are not whole numbers because they take into account the average mass of all the isotopes of that element, which have different masses due to varying numbers of neutrons. This results in a weighted average that is not a whole number.

Whole numbers are 0 , 1 , 2 , 3 etc.. (dont contain negative) Integers are -2 , -1 , 0 , 1 , 2 , 3, ie they CONTAIN whole numbers

You can't change a whole number to a decimal. A decimal and a whole number are both numbers. A decimal is just a number lower than a whole number, or a number in between two 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.
add? dont you mean subtract?
