atomic mass s

Atomic Mass is the Weighted Average Mass of Isotopes — For example, the mass of an atom of 1H is 1.008 u, the mass of an atom of 16O is 15.995 u, and the. The atomic mass of an atom is an empirically measured property, which is equivalent to the sum mass of protons, neutrons, and electrons that make up the atom (. atomic mass, the quantity of matter contained in an atom of an element. It is expressed as a multiple of one-twelfth the mass of the carbon-12 atom, The atomic mass (ma) is the mass of an atom at rest, most often expressed in unified atomic mass units. The atomic mass may be considered to be the total mass. The atomic mass of an isotope and the relative isotopic mass refers to a certain specific isotope of an element. Because substances are usually not isotopically.
