تعريف (he) helyum في التركية الإنجليزية القاموس.
- (Nükleer Bilimler) helium
- A form or sample of the element
- A colorless and inert gas, and the second lightest chemical element (symbol He) with an atomic number of 2 and atomic weight of 4.002602
- second lightest gas; does not cause problems of narcosis seen with nitrogen, and is therefore used for very deep diving
- A gaseous element found in the atmospheres of the sun and earth and in some rare minerals
- It is a decomposition product of the radium emanation
- A colorless, odorless, tasteless, inert gaseous element Jovian planets are rich in hydrogen and helium whereas the terrestrial planets are not
- A colorless, nontoxic, noncombustible gas Uses include welding, leak detection, chromatography, geological dating, diving Hazard: Simple asphyxiant
- 98 compared with hydrogen, and is more difficult to liquefy than the latter
- Second lightest gas; dies not cause problems of narcosis to the same extent as seen with nitrogen, and is therefore used for very deep diving
- Helium is a very light gas that is colourless and has no smell. a gas that is lighter than air and is used to make balloons float. It is a chemical element : symbol He (helios ; because it was discovered in the sun's spectrum). Chemical element, chemical symbol He, atomic number
- wt
- The empire of the grandfather of Dejah Thoris
- One of the lightest elements, second only to hydrogen Helium is one of the harmless by-products of nuclear fusion It is also used in balloons and will make your voice squeaky if you inhale it Don't inhale too much, though Your body needs a little oxygen, too - WebElements: Helium
- the second lightest and second most abundant element in the Universe The helium atom consists of a nucleus of two protons and two neutrons surrounded by two electrons Helium was first discovered in our Sun Roughly 5 percent of our Sun is helium
- a very light colorless element that is one of the six inert gasses; the most difficult gas to liquefy; occurs in economically extractable amounts in certain natural gases (as those found in Texas and Kansas)
- An inert gas A colorless, monatomic element which is found to occur in dry air to the extent of only 0 000524 percent by volume Helium is very light, having a molecular weight of only 4 003 and specific gravity referred to air of 0 138 Because helium is non-inflammable and has a lifting power 92 percent of that of hydrogen, it is widely used as the inflation gas for meteorological balloons
- Helium has a density of 1
- {i} inert gaseous element
- a chemical element usually in gaseous state
- An inert gas that is lighter than air (either Nike AIR or normal breathing air) Predominately sourced from natural gas wells in Texas Converse introduced a basketball shoe with helium in November 1999, followed by a helium-cushioned skate shoe in 2000
