Percent Abundance vs. Relative Abundance: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on December 3, 2023
Percent abundance refers to the proportion of a specific isotope or element in a mixture, expressed as a percentage; relative abundance is a comparison of the abundance of different species or isotopes without a specific unit.

Key Differences

Percent abundance quantifies how much of a certain isotope is present in a natural mixture, expressed as a percentage; while relative abundance compares the presence of different isotopes or species relative to each other without necessarily using percentages.

Relative abundance is often used in ecological contexts to compare different species within an ecosystem; whereas, percent abundance, on the other hand, is typically used in chemistry to express the composition of isotopes in a sample.

In measuring isotopes, percent abundance gives a precise numerical value indicating the proportion of each isotope in a sample; relative abundance, however, might simply indicate which isotope is more prevalent, without exact percentages.
