Question

What is the ratio of abundance of chlorine isotopes with atomic masses 35 and 37?

• A. \(1:1\)
• B. \(3:1\)
• C. \(1:2\)
• D. \(5:3\)

Hint:

The ratio of isotopes in nature is determined by their relative abundance.

Answer 1

The Correct Option is B

The natural abundance of chlorine isotopes is approximately 75\% for \(^{35}\)Cl and 25\% for \(^{37}\)Cl. This corresponds to a ratio of 3:1 for the isotopes \(^{35}\)Cl and \(^{37}\)Cl.
