[{"from": "human", "value": "Describe this molecule. [Zr]"}, {"from": "gpt", "value": "The molecule appears as a gray amorphous powder. May ignite spontaneously and burn with explosive violence. Ignitable by static electricity. Small amounts of moisture may promote the ignition of zirconium. Continues to burn despite immersion in water and does so with greater intensity than in air. Used to make corrosion-resistant alloys, in pyrotechnics, and for many other uses."}]
