Aug 13, 2007 · Appreciate it if someone could show me how to work the following percentage abundance problem: Chlorine has two isotopes: chlorine-35 (mass 34.9689 amu) and chlorine-37 (mass 36.9659 amu). What is the percentage abundance of these two isotopes if chlorine's atomic mass is 35.453? Thanks!
Mar 08, 2017 · Being able to identify ions and isotopes of atoms and knowing how to read and write their symbols is an important skill in chemistry. If you're feeling unsure of yourself, you can review how to find the number of protons, neutrons, and electrons in an atom or ion.
The half-life tells us how radioactive an isotope is (the number of decays per unit time); thus it is the most commonly cited property of any radioisotope. For a given number of atoms, isotopes with shorter half-lives decay more rapidly, undergoing a greater number of radioactive disintegrations per unit time than do isotopes with longer half ...
