Lithium relative atomic mass
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 ... WebThere was no periodic increase in the atomic mass between two elements. so it is not easy to predict how many elements can come between two elements . For example, the difference of atomic mass between element A and B =2.5u, difference between element B and C =3u, difference between element C and D =1u,
