This trend results in cesium having a melting point near human body temperature, making it a liquid under specific conditions. Fire suppression must be done with dry sand or Class D metal fire extinguishers, as standard water or carbon dioxide extinguishers will exacerbate the reaction.
Alkali Metals Always Bonded to Halides and Silicates in Nature
As one moves down the group from lithium to francium, the atomic radius increases, leading to a gradual decrease in melting and boiling points. Lithium reacts steadily with water, producing lithium hydroxide and hydrogen gas.
Potassium compounds are vital in fertilizers, ensuring plant growth and crop yield. The extraction process requires electrolysis of the fused chloride or hydroxide, conducted in an inert atmosphere to prevent immediate reaction with air.
Alkali Metals Always Bonded to Halides and Silicates in Nature
They are never encountered in a pure, elemental state in nature, always existing as ionic compounds within minerals and salts. Reaction with Non-Metals Their reactivity extends to non-metals, where they form ionic compounds with extreme vigor.
