As they are isobars, they have the same relative molecular mass.
The atomic mass of Li, which stands for lithium, is approximately 6.94 atomic mass units (u).
The atomic number is 3.
Lithium's atomic symbol is Li. It's atomic number is 3, and it's relative atomic mass (Ar) is 6.9 Lithium is in Group 1 and is highly reactant, most likely to give an electron when forming a compound
Among these three elements, Cl has the greatest mass, as can be seen from any periodic table or other reference work that shows atomic masses.
Naturally occurring lithium contains two isotopes. The common one has an atomic mass of 7. About one per cent of the lithium has an atomic mass of 6.The atomic mass of Lithium-Li is 6.941 grams.

The normal chemical symbol is used for the isotope with the addition of the atomic number (Z) at the lower left of the symbol and the atomic mass number (A) at the upper left as shown X.For example Li and Li represent two isotopes of lithium.Since all lithium isotopes have an atomic number Z=3, this number is usually omitted and the isotopes are represented by the symbols Li and Li. These are sometimes written as Lithium-6 and Lithium-7 or Li-6 and Li-7.
This is the third element Lithium: 6.94 g is the mass of 1 mole Li. The mass in grams of one mole of any element is exactly its atomic mass (in a.m.u.)
A gram atomic mass of helium (He) contains the same number of atoms as 1 mole of helium. Since 1 mole of any substance contains approximately 6.022 x 10^23 atoms, a sample of helium with a gram atomic mass would contain that same number of atoms.
The element with the least mass in Period 2 is Lithium (Li). It has an atomic mass of approximately 6.94 g/mol
