16 de ago. de 2024 · Helium, chemical element, inert gas of Group 18 (noble gases) of the periodic table. The second lightest element, helium is a colorless, odorless, and tasteless gas that becomes liquid at -268.9 degrees Celsius. The boiling and freezing points of helium are lower than those of any other known substance.
After hydrogen, helium is the second most abundant element in the universe. It is present in all stars. It was, and is still being, formed from alpha-particle decay of radioactive elements in the Earth. Some of the helium formed escapes into the atmosphere, which contains about 5 parts per million by volume.
El helio es un elemento ligero que es único debido a que es un producto de la Tierra y no proviene de los restos de estrellas que existían antes de que la Tierra se formara. Todo el helio que existe en la Tierra se ha formado durante la historia del planeta.
El helio (del griego: ἥλιος [hḗlios] ‘ Sol ’, por haberse inferido en 1868 su existencia en la atmósfera solar) 2 es el elemento químico de número atómico 2, símbolo He y peso atómico estándar de 4,002602.
Atom number: 2; atomic weight: 4.0026; melting point: -272 °C (0.95 K); boiling point: -269 °C (4.2 K). Helium is the lightest of the noble gases, and heads Group 18 of the Periodic Table. It is colourless, odourless, and chemically unreactive. Helium has two stable isotopes, helium-4 and helium-3. Neither is radioactive.
The second most abundant element in the universe, helium is scarce on Earth. A product of nuclear fusion and radioactive decay, it is the lightest noble gas, colorless, odorless, and inert with a low boiling point.
Helium is combined with oxygen to create a nitrogen free atmosphere for deep sea divers so that they will not suffer from a condition known as nitrogen narcosis. Liquid helium is an important cryogenic material and is used to study superconductivity and to create superconductive magnets.

helium, Chemical element, chemical symbol He, atomic number 2. A noble gas, it is colourless, odourless, tasteless, completely unreactive, and nontoxic. First found by spectroscopy of the Sun’s atmosphere in 1868, it is the second most abundant and second-lightest element in the universe (after hydrogen).
The Helium Network Token ("HNT") is the native cryptocurrency of the Helium Network and is the only token that can be burned to create Data Credits and send device data. Subnetwork tokens (IOT and MOBILE) are backed and redeemable for HNT.
2 de sept. de 2021 · Helium is a disintegration product of radioactive substances, so it is found in ores of uranium, radium, and other elements. Most of Earth's helium dates back to the planet's formation, although a small amount falls to Earth within cosmic dust and some is produced via beta decay of tritium.
