Isotopes have the same atomic number and different mass. This difference is due to different number of neutrons in them. That is why the mass of chlorine comes to be 35.5, a fraction.

How the atomic mass of an element is affected by the distribution of its isotopes in nature?
The atomic mass of an element is the average of its isotopes, weighted by abundance in nature.
Who invented isotopes?
Isotopes were not invented - they exist in nature. They were discovered when the atomic mass of Chlorine was measured at 35.5
Is neon radioactive?
No radioactive isotopes of neon are ordinarily found in nature. All elements have radioactive synthetic isotopes, however.
Which elements found in nature have mainly radioactive isotopes?
uranium ores
How is the atomic mass of an element is affected by the distribution of its isotopes in nature?
Isotopes have a different amount of Neutrons. The atomic mass is the sum of Protons and Neutrons. Therefore having a different number of Neutrons makes the atomic mass greater. Or vice versa. Boom. Solved.
Most elements in nature are?
isotopes

Which of these are elements that occur most in nature?
isotopes
Is an average mass of the different isotopes of the element?
Yes, weighted by how often the isotopes are found in nature.
What is the value that depends on the distribution of the elements isotopes in nature and the masses of those isotopes?
This value is the atomic weight.

What is an average of the masses of all the isotopes that occur in nature For an element?
The weighted average for all isotopes that occur in nature for an element is its atomic weight listed on the Periodic Table of the elements.
Is boron radioactive?
There are no radioactive isotopes of boron that are ordinarily found in nature. All elements have synthetic radioactive isotopes, however.
Is neon radioactive?
No radioactive isotopes of neon are ordinarily found in nature. All elements have radioactive synthetic isotopes, however.
Is carbon synthetic or can it be found in nature?
Carbon can certainly be found in nature, but some of its radioactive isotopes are synthetic.
Which elements found in nature have mainly radioactive isotopes?
uranium ores
