Flexi Says: Gallium is a shiny metal with a relatively low melting point of ~30 degrees Celsius. However, it has an unusually high boiling point of 2204 degrees Celsius. It easily bonds with other metals to form soft-melting alloys. It is majorly used in semiconductors and LEDs. It is one of the four metals which are liquid at/near room temperature (others are mercury, rubidium and caesium) and it is the least reactive and non-toxic among these.
