[" The percentage of naturally pecuming is stopes "^(35)Cl" and "^(37)Cl" isotopes that "],[" accounts for atomic mass of chilentine as "35.45" is "]

Calculate the percentage of the naturally occuring isotopes ""^(35)Cl and ""^(37)Cl that accounts for the atomic mass of chlorine taken as 35.45.

Chlorine has two isotopes "_17^35Cl And "_17^37Cl in the ratio 3:1 . Calculate the average atomic mass of chorine.

(a) What are radioactive isotopes ? Give two examples of radioactive isotopes (b) Give any two uses of ratioactive isotopes (c) An element Z contains two naturally occuring isotopes ._(17)^(35) Z and ._(17)^(37)Z . If the average atomic mass of this element be 35.5 u, calculate the percentage of two isotopes.

Chlorine has two naturally occuring isotopes, ""^(35)Cl " and " ""^(37)Cl . If the atomi mass of Cl is 35.45, the ratio of natural abundance of ""^(35)Cl " and " ""^(37)Cl is closest to

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

Natural chlorine consists of two isotopes : 75% ""_(17)^(35)Cl and 25% ""_(17)^(37)Cl . Calculate the average atomic mass of chlorine .
