Answer: 7.0160034 Da What is isotopic mass for Lithium-7 isotope? … The alkali metals are also called the lithium family, after its leading element. Like the other alkali metals (which are sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr)), lithium has a single valence electron that, in the presence of solvents, is easily released to form Li . Because of this, lithium is a good conductor of heat and electricity as well as a highly reactive element, th…
