Why are the elements on the periodic table not arranged by mass? a. similar elements have such different masses that this would lead to a completely random arrangement of elements.
b. atoms are so small that it would make little sense to talk about their masses.
c. this would not allow all of the elements with similar properties to be lined up with each other.
d. atoms with similar masses are so different from each other that this would lead to a random arrangement of atoms.​

How do cfcs cause ozone depletion? how do cfcs cause ozone depletion? ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation breaks down cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks two oxygen atoms away from ozone, leaving behind a paired oxygen molecule. ultraviolet radiation creates cfcs, molecules containing chlorine. chlorine then breaks one oxygen atom away from ozone, leaving behind a paired oxygen molecule.
