Atomic Mass

Atomic mass, a fundamental concept in chemistry and physics, refers to the mass of an atom. It plays a crucial role in understanding the behavior of elements and their interactions in chemical reactions. By measuring atomic mass, scientists can determine the relative abundance of isotopes within an element and calculate various properties such as molar mass and molecular weight. This introductory paragraph sets the stage for exploring the significance of atomic mass in the context of atomic structure, periodic trends, and the composition of matter.
