The atomic mass of an element is a measure of the amount of matter contained in an atom of that element, and it is typically expressed in atomic mass units (amu). The periodic table is a chart that organizes all of the known elements according to their atomic properties, including their atomic mass. In this article, we will explore the atomic mass of the first 30 elements on the periodic table, starting with hydrogen and ending with zinc.

These elements represent the building blocks of matter, and understanding their atomic mass can provide insight into the chemical and physical properties of the substances they form.
