The main reason that the Atomic Mass of elements is not a whole number is due to the presence of different isotopes - these have the same number of protons in the nucleus but a different number of neutrons - so their masses are different even though chemically they are identical.
The two isotopes of Chlorine are 35Cl- (75.77%) and 37Cl (24.23%) giving an overall "average" mass of 35.4527.

What is the atomic number for the atom?
We use atomic number for recognize chemical elements. atomic number means, how many protons are there in a single atom.
What does the atomic number say about an atom?

What is the atomic number of ypour element?
We use atomic number for recognize chemical elements. atomic number means, how many protons are there in a single atom.
How many elements have the same atomic numberin the periodic table?
None. All elements have a unique atomic number designated by the number of protons contained in their nucleus.
How many Scientific Elements are there?
There are currently 118 known elements on the periodic table, with elements ranging from hydrogen (atomic number 1) to oganesson (atomic number 118). These elements are organized based on their atomic number and properties, and each element has its own unique characteristics.
How many protons does an element have when the atomic number is 8?
If an elements atomic number is 8, that means it also has 8 protons.
What is the atomic number of Wheat?
There is no atomic number for wheat, because wheat is not an element, it is made up of many elements. I don't know exactly why you are asking this, but if someone told you there is an atomic number for wheat, then you are mistaken, and they are probably playing a trick on you, and embarrassing you.

How many elements have an atomic number greater than iodine?
i believe it is 57 do.If im wrong then im wrong im very sorry if i am.
Can two elements have same atomic number?
No, two elements cannot have the same atomic number. The atomic number of an element is determined by the number of protons in its nucleus, which is unique to each element. Therefore, elements with different atomic numbers will have different numbers of protons and thus different chemical properties.
How many elctrons does mercury have?
If you have a periodic table of elements it is the atomic number.or if you don't it is 80 electrons, same as the atomic number which is also the number of protons.
