Zinc is a metallic element with the atomic number 30. It is found in nature most often as the mineral sphalerite. Though excess zinc in harmful, in smaller amounts it is an essential element for life, as it is a cofactor for over 300 enzymes and is found in just as many transcription factors. Metal phosphides are hydrolysed to phosphine upon contact with water or stomach acid. Phosphine is a colorless, flammable, explosive, and toxic gas. (L980, L48, L49, L75)"}]
