THE METAL THAT CAN MELT IN YOUR HAND - Video

Gallium is a chemical element with the symbol Ga and atomic number 31. What makes this metal unusual is its very low melting point, approximately 29.76°C. Because this temperature is only slightly above room temperature and close to human body temperature, solid gallium can melt when it receives enough heat from a person's hand. Under suitable conditions, a piece of solid gallium gradually transforms into a silvery liquid. However, gallium does not necessarily melt immediately when touched. The result depends on factors such as the surrounding temperature, the size of the sample, its purity, and how long it is exposed to heat. Gallium is also important in modern technology. Compounds such as gallium arsenide and gallium nitride are used in semiconductor technology and various electronic devices. So, this unusual metal is not only fascinating to watch—it also plays an important role in modern technology.
