What is the atomic weight of chlorine isotopes?

The atomic weight of chlorine isotopes varies due to differences in their neutron count. Chlorine primarily exists in two stable isotopes:

Chlorine Isotopes

• Chlorine-35: This isotope has an atomic weight of approximately 34.968 amu (atomic mass units). It contains 17 protons and 18 neutrons.
• Chlorine-37: This isotope has an atomic weight of about 36.966 amu. It consists of 17 protons and 20 neutrons.

The average atomic weight of chlorine, considering the natural abundance of these isotopes, is about 35.453 amu. This value reflects the weighted average based on the relative amounts of each isotope found in nature.
