Overview
Atomic mass and isotopes are fundamental concepts in chemistry that help us understand the properties and behaviors of elements. Atomic mass is not just a simple number; it reflects the average mass of an element's isotopes, which can vary in their neutron count. Isotopes play a crucial role in vari...
