Answer:

Gallium is a metal which, due to its melting point of 29.76°C, will turn to liquid in your hand. And, unlike mercury, pure gallium is safe to handle. ... Liquid metal embrittlement is a phenomenon where ductile metals, like aluminium, become brittle, when exposed to certain liquid metals, like gallium.

Explanation:

Gallium (Ga), chemical element, metal of main Group 13 (IIIa, or boron group) of the periodic table. It liquefies just above room temperature.

Gallium (Ga), chemical element, metal of main Group 13 (IIIa, or boron group) of the periodic table. It liquefies just above room temperature.Gallium was discovered (1875) by French chemist Paul-Émile Lecoq de Boisbaudran, who observed its principal spectral lines while examining material separated from zinc blende. Soon afterward he isolated the metal and studied its properties, which coincided with those that Russian chemist Dmitry Ivanovich Mendeleyev had predicted a few years earlier for eka-aluminum, the then-undiscovered element lying between aluminum and indium in his periodic table.

It is extracted as a by-product from zinc blende, iron pyrites, bauxite, and germanite.Gallium is silvery white and soft enough to be cut with a knife. It takes on a bluish tinge because of superficial oxidation. Unusual for its low melting point (about 30 °C [86 °F]), gallium also expands upon solidification and supercools readily, remaining a liquid at temperatures as low as 0 °C (32 °F). Gallium remains in the liquid phase over a temperature range of about 2,000 °C (about 3,600 °F), with a very low vapour pressure up to about 1,500 °C (about 2,700 °F), the longest useful liquid range of any element. The liquid metal clings to (wets) glass and similar surfaces. The crystal structure of gallium is orthorhombic. Natural gallium consists of a mixture of two stable isotopes: gallium-69 (60.4 percent) and gallium-71 (39.6 percent). Gallium has been considered as a possible heat-exchange medium in nuclear reactors, although it has a high neutron-capture cross section.

Aluminium also possess these qualities of gallium . Therefore ,it is said that aluminium is similar to gallium.
