How can i find the abundance of an isotope?
Go to the site below, www.webelements.com, click on the element and scroll down the right hand side to "nuclear properties." Under that heading is isotopes. The abundance is given there.

well i have two isotopes and i am given only one abundance for one. I need to find the other abundance for the other isotope to continue. Will that help me?
The relative abundances of all stable isotopes are given at the webelements link provided by DrBob . His example was for silver but you can connect from there to the other elements.
If you know there are ONLY two isotopes and you know the abundance of one of them, then the other one is 100% - percent of the one you have.
To find the abundance of an isotope, you can follow these steps:
1. Identify the isotopes: Determine the different isotopes of the element you are interested in. Isotopes are atoms of the same element that have different numbers of neutrons.
2. Look up atomic masses: Find the atomic masses of each isotope. Atomic masses can be found on the periodic table or in a reference book. The atomic mass is the weighted average of the masses of all the isotopes of an element, taking into account their respective abundances.
3. Calculate the abundance: Once you have the atomic masses of the isotopes, you can calculate the abundance of each isotope using the following formula:
Abundance = (Atomic mass of isotope / Atomic mass of element) x 100
This formula gives you the percentage abundance of each isotope.
By following these steps, you will be able to determine the abundance of a specific isotope of an element.
