tell me EVERYTHING you know about helium?

Question

give me some good vocabulary for helium... i can't find it on the internet so if u can find some good vocab, please tell me. i would appreciate it. thnx!

Answer 1

Its a very inert, extremely low density element which is low on the periodic table and gaseous at common atmospheric temperature and pressure. And when you breath it in it makes you talk funny. That last one is most important.

Answer 2

Helium is a colorless, odorless, tasteless chemical element. It is the most unreactive of the noble gases and therefore the least chemically-active chemical element on the periodic table. Its boiling and melting points are the lowest among the elements; except in extreme conditions, it exists only as a gas. At temperatures near absolute zero, it is a superfluid, a nearly frictionless phase of matter with unusual properties.

After hydrogen, helium is the second lightest element and the second most abundant element in the universe, created during big bang nucleosynthesis and to a lesser extent from nuclear fusion of hydrogen in stars. On Earth, helium is primarily a product of the radioactive decay of much heavier elements, which emit helium nuclei called alpha particles; it is found in significant amounts only in natural gas, from which it is extracted at low temperatures by fractional distillation.

First detected in 1868 by French astronomer Pierre Janssen as an unknown yellow spectral line signature in the light of a solar eclipse, helium was separately identified as a new element later that year by English astronomer Norman Lockyer. Its presence in natural gas in large, useable amounts was identified in 1905. Helium is used in cryogenics, as a deep-sea breathing gas, for inflating balloons and airships, and as a protective gas for many industrial purposes, such as arc welding. Inhaling a small amount of the gas temporarily changes the frequency of a person's voice; however, caution must be exercised as helium is an asphyxiant.

Answer 4

The symbol is He. It's an extremely light, nonflamable, odorless, gaseous element. It is lighter than air, it is used in blimps, and during WW11 blimps would patrol the coastlines of the usa looking for German submarines lurking along the eastern Atlantic coast sinking mainly supply ships bound for Europe. There are very few blimps left. Sorry, in high school chemistry i could have given you more info but that was 1972.

If you type in helium, then click 'look it up' , then click 'try' it will give you an answer. Scroll down in the 'nouns' box
All I know about helium is it makes balloons float, makes you talk funny when inhaled and probably explodes with fire

Answer 6

Answer 7

it is a harmless gas ... non active ..

Answer 8

sorry im not that smart
