(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

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
