@spectrometry.mp4: Lithium is the third element on the periodic table, with atomic number 3 and the chemical symbol Li. It is the lightest alkali metal and a soft, silvery metal with high chemical reactivity. A lithium atom contains three protons and three electrons, with one valence electron that strongly influences its chemical behavior. Lithium readily forms Li⁺ ions and commonly produces ionic compounds such as lithium chloride and lithium carbonate. Lithium is especially important in electrochemistry, batteries, materials science, and energy storage. Lithium-ion batteries use lithium compounds and electrochemical reactions to store and release electrical energy, making lithium essential to electric vehicles, smartphones, laptops, renewable energy storage, and portable electronics.
