how many electrons are there in copper?
29
63
34
92

35Cl isotope
37Cl isotope
neither of these
Answer explanation
we can see that a naturally occurring sample of chlorine must contain more of the 35CI isotope than the 37CI isotope. This is because the relative atomic mass is closer to 35 than to 37.
