Percentage Abundance Calculator: Find Isotopic Ratios with Ease

April 24, 2025 3 min read

In chemistry, elements often exist as a mixture of different isotopes. Isotopes are atoms of the same element that have the same number of protons but a different number of neutrons, leading to variations in their atomic mass. The percentage abundance refers to the relative amount of each isotope present in a naturally occurring sample of an element. Knowing this is crucial for accurate calculations and a deeper understanding of elemental behavior. Figuring this out manually can be cumbersome but now you can easily solve these complex math problems with just a few clicks!
