WebAtomic Mass of Lithium. Atomic mass of Lithium is 6.941 u. The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. The atomic mass is carried by the atomic nucleus, which occupies only about 10 -12 of the total ... WebThe atomic mass of an element can be described as the total mass of one atom of the given element. Its unit is called the unified atomic mass unit and is denoted by the symbol ‘u’. Standard atomic weight is used to give the value of the mean of the atomic masses in a mixture of isotopes in a given sample of an element.
