Gallium Element in Periodic Table | Atomic Number Atomic Mass

Gallium Element:

Gallium is an element in the thirteenth group and fourth period of periodic table and it has the symbol Ga and atomic number 31. Gallium is a soft, silvery metal and thus has similarities to the other metals of the group, aluminum, indium and thallium. It  does not occur as a free element in nature; rather, it exists in trace amounts in zinc ores and in bauxite. Gallium contains 31 isotopes, ranging in mass number from 56 to 86, but only two of these isotopes, ⁶⁹Ga and ⁷¹Ga are stable which occur naturally.

Gallium Element Uses:

• Gallium is used in electronic circuits, semiconductors and light-emitting diodes (LEDs).
• It is also useful in high-temperature thermometers, barometers, pharmaceuticals and nuclear medicine tests.
• Gallium nitride is also used as semiconductor. It is used in Blu-ray technology, mobile phones, blue and green LEDs and pressure sensors for touch switches.
• Gallium bonds easily with most metals and is particularly used to make low-melting alloys.
