WebThe atomic mass ( ma or m) is the mass of an atom. Although the SI unit of mass is the kilogram (symbol: kg), atomic mass is often expressed in the non-SI unit dalton (symbol: Da) – equivalently, unified atomic mass unit (u). 1 Da is defined as 1⁄12 of the mass of a free carbon-12 atom at rest in its ground state. [1] WebNov 21, 2024 · Mass Number of Oxygen Mass numbers of typical isotopes of Oxygen are 16; 17; 18. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N.
