![]() ![]() By definition, an atom of carbon with 6 neutrons, carbon-12, has an atomic mass of 12 amu. The atomic mass of a single atom is basically its total mass and is usually expressed in atomic mass units or amu. The notation of an atom is given below.Ī property strongly related to an atom’s mass number is its atomic mass. If you want to calculate the number of neutrons in an atom, you can simply deduct the number of protons, or atomic numbers, from the mass number. Mass Number = Number of protons + Number of neutrons Together, the number of protons and the number of neutrons dictates an element’s mass number. On the other hand, the number of neutrons for a given element can differ. The atomic number is the number of protons there in an atom. In fact, the number of protons dictates what atom we are looking at (e.g., all atoms with 6 protons are carbon atoms). ![]() Here, we will discuss important concepts of atomic number and atomic mass.Ītomic Number, Atomic Mass, and Relative Atomic MassĪtoms of each element consist of a particular number of protons. The atomic number and mass number are the basic concepts of atomic structure. The mass number is defined as the total number of protons and neutrons of an element. Hence atomic number is useful in differentiating one element from another. The electronic configuration of Cesium will be 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p6 6s1.The atomic number is defined as the total number of protons or electrons in an element.
