Question

What is the relative abundance of the two isotopes when chlorine is an element of atomic number 17 and atomic mass 35.5? It has natural occurring isotopes of mass number 35 and 37.

Answer 1

The relative abundance of isotopes can vary depending on the source of the element. However, for natural chlorine, approximately 75.53% of the isotopes are chlorine-35 (mass number 35) and about 24.47% are chlorine-37 (mass number 37). These values represent the average relative abundance observed in nature.
