科学家预言21世纪金属元素的明星将是提（Li）。锂能够成为明星是因为它有3大特性，能在相关领域里大显身手。键是金属中最轻的元素（比重0．534），呈银白色，是既轻又软的高能金属。专家称其为“金属味精”，也就是说在其他金属中加入一点理就能改变原来金属的性质。例如，冶 Scientists predict that the stars of the 21st century metal will be Li. Lithium can become a star because it has three major features that can show their talents in related fields. Key is the lightest element in the metal (specific gravity 0.534), silver-white, is both light and soft high-energy metal. Experts call it “metal monosodium glutamate,” which means that adding a bit of other metals can change the nature of the original metal. For example, Ye
