Gallium is a chemical element with Ga as symbol and atomic number 31.
Elemental gallium are gallium compounds that have trace amounts in zinc ores and in bauxite.
The melting point of an elemental gallium is at 302.9146 K or 29.7646°C or 85.5763°F, above room temperature.
A normal human body temperature is at 37°C or 98.6°F; higher than the melting point of gallium. So, if one holds a gallium in his hands, the metal will melt.
