[" In chlorine gas,ratio of "Cl^(35)" and "],[Cl^(37)is],[" (a) "1:3],[" (b) "3:1],[" (c) "1:1],[" (d) "1:4]

""_(17 ) Cl^(35) and ""_(17) Cl ^(37) are ________ .

""_(17 ) Cl ^(35 ) and ""_(17) Cl^(37 ) are _________.

What is the difference in the structures of Cl^35 and Cl^37 nuclei?

What are ._(17)^(35) Cl and ._(17)^(37) Cl ? Why

Natural chlorine is composed of two isotopes ""_(17)Cl^(35) and ""_(17)Cl^(37) with masses 34.968 and 36.968, respectively. If their relative abundance are 75.18% and 24.22% respectively, calculate the composite atomic mass of the natural chlorine.

Both ""^(35)Cl and ""^(37)Cl have the same valency . Why ?
