Gallium has 30 known isotopes, ranging in mass number from 60 to 89. Only two isotopes are stable and occur naturally, gallium-69 and gallium-71. Gallium-69 is more abundant: it makes up about 60.1% of natural gallium, while gallium-71 makes up the remaining 39.9%.
118 chemical elements have been identified and named officially by IUPAC.A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z).
Gallium was discovered by French scientist Paul-Émile Lecoq de Boisbaudran, who named it in honor of France ("Gallia" in Latin); allegations were later made that he had also named it for himself, as "gallus" is Latin for "le coq", but he denied that this had been his intention. [8]
Chemical symbols are the abbreviations used in chemistry, mainly for chemical elements; but also for functional groups, chemical compounds, and other entities. Element symbols for chemical elements, also known as atomic symbols, normally consist of one or two letters from the Latin alphabet and are written with the first letter capitalised.
Gallium is a chemical element with symbol Ga and atomic number 31. Gallium may also refer to: Gallium experiment, a neutrino detection experiment also known as GALLEX; Gallium scan or gallium imaging, a method for the detection of infections and cancers; Gallium3D, a software library for 3D graphics acceleration
Similarly, the name helium is derived from the Greek word for the Sun (Ἢλιος, Helios), as the first evidence for helium came in the form of distinctive emission lines from the Sun that were not explainable by any of the known elements in the 1870s. [37] Tellurium is named after the Latin word tellus, meaning "earth".
It means getting the rest of the world addicted to China's products — not just cheap manufactured goods but also advanced technology like semiconductors, batteries, and AI and the commodities ...
Gallium is one of the chief components of blue LEDs. Gallium and its derivatives have only found applications in recent decades. Gallium arsenide has been used in semiconductors, in amplifiers, in solar cells (for example in satellites) and in tunnel diodes for FM transmitter circuits. Gallium alloys are used mostly for dental purposes.
