Helium | references | in Wikidata. Helium is a chemical element with symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the elements. After hydrogen, helium is the second lightest and second most abundant element in the observable universe, being present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined. Its abundanc

- Helium is a chemical element with symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas that heads the noble gas group in the periodic table. Its boiling and melting points are the lowest among all the elements.n Earth it is relatively rare — 5.2 ppm by volume in the atmosphere. Most terrestrial helium present today is created by the natural radioactive decay of heavy radioactive elements (thorium and uranium, although there are other examples), as the alpha particles emitted by such decays consist of helium-4 nuclei.

Mercury (element) Most mercury(I) compounds are diamagnetic and feature the dimeric cation, Hg 2+ 2. Stable derivatives include the chloride and nitrate. Treatment of Hg(I) compounds complexation with strong ligands such as sulfide, cyanide, etc. induces disproportionation to Hg2+ and elemental mercury.

- Thorium is a chemical element with symbol Th and atomic number 90. A radioactive actinide metal, thorium is one of only three radioactive elements that still occur naturally in large quantities as a primordial element (the other two being bismuth and uranium).horium is also used as an alloying element in TIG welding electrodes. It remains popular as a material in high-end optics and scientific instrumentation; thorium and uranium are the only radioactive elements with major commercial applications that do not rely on their radioactivity.

What is Stress? In his later years, when asked to define stress, he told reporters, “Everyone knows what stress is, but nobody really knows.”. As noted, stress is difficult to define because it is so different for each of us. A good example is afforded by observing passengers on a steep roller coaster ride.Some are hunched down in the back seats, eyes shut, jaws clenched and white knuckled with an iron grip on the retaining bar.hat distinguished the passengers in the back from those up front was the sense of control they had over the event. While neither group had any more or less control their perceptions and expectations were quite different. Many times we create our own stress because of faulty perceptions you can learn to correct.

10 Mercury Facts (Element) 1 The modern element symbol for mercury is Hg, which is the symbol for another name for mercury: hydrargyrum. 2  Hydrargyrum comes from Greek words for water-silver (hydr-means water, argyros means silver). 3  Mercury is a very rare element in the Earth's crust. 4  It accounts for only about only 0.08 parts per million (ppm). Mercury is a very rare element in the Earth's crust. 2  It accounts for only about only 0.08 parts per million (ppm). 3  Mercury generally is not allowed on aircraft because it combines so readily with aluminum, a metal that is common on aircraft.
