Who is the discoverer of the helium?
The discovery of heliumHelium was discovered by the French astronomer Pierre Jules Cesar Janssen during a total solar eclipse in Guntur, India, in 1868. The same spectral emission lines were noted by the English astronomer Norman Lockyer, also in 1868, who proposed the name "helium," after Helios, the Sun God of Greek mythology. In 1895 Sir William Ramsay separated for the first time helium from air in laboratory; the same year this experiment was repeated independently by Per Theodor Cleve and Nils Langlet in Sweden.French Astronomer Pierre Jannssen.
Is Helium natural or man made?
No. Helium is an element.No, Helium is not manmade. It naturally occurs in nature. It can be artificially produced though.It is a noble gas on the periodic table, atomic number 2.
Origin of the name helium?
This name arose because helium was first observed, albeit indirectly, in the sun. In 1868 Jules Janssen and Norman Lockyer noticed a hitherto unknown yellow spectral line (at about 587 nanometres) in light from the sun's chromosphere. Lockyer postulated that this was due to a previously unknown element, which he named helium from the Greek helios (sun). It wasn't until somewhat later that century, in 1882, that Luigi Palmeri detected the first evidence of Earth-based helium, when he observed the same 587 nm line being emitted from lava from Mount Vesuvius. Another decade later (1895) Sir William Ramsey became the first person to actually isolate terrestrial helium.
How was helium discovered and when?
The first evidence of helium was observed on August 18, 1868 as a bright yellow line with a wavelength of 587.49 nanometers in the spectrum of the chromosphere of the Sun.
Did Marie Curie discover gravity?
No, Sir Isaac Newton did.
Who discovered helium and when did they discover it?
Pierre Jules Cesar Janssen and Norman Lockyer&Edward Frankland in 1868. See also: http://www.vanderkrogt.net/elements/elem/he.HTML. --------- Sir William ramsay 1895 contributed to the process as did Joseph lockyer 1869
Who is Norman lockyer?
Sir Joseph Lockyer (17 May 1836-16 August 1920) was an English scientist and astronomer. Along with the French scientist Pierre Janssen he is credited with the discovrery of helium.

What is the date that helium was discovered?
hi, helium was first observed in the year 1868 by Pierre Janssen and Norman Lockyer. On March 26, 1895, Scottish chemist Sir William Ramsay isolated helium on Earth.
When discover helium?
Helium was discovered in 1868 as a new spectral line in light from the sun by French astronomer Jules Janssen during a total solar eclipse in Guntur, India. In the same year, Norman Lockyer, an English Astronomer concluded that the new spectral line was caused by an element in the Sun unknown on Earth and named it Helium. In 1882, Italian physicist Luigi Palmieri detected helium on Earth for the first time. March 26, 1895 Sir William Ramsay, a Scottish chemist, isolated helium on Earth.
How Long Did Sir Joseph Norman Lockyer Live For?
He was born on the 17th of May 1836 and died on the 16th of August 1920, at the age of 84.

Who found helium?
Helium, the second most abundant element in the universe, was discovered on the sun before it was found on the earth. Pierre-Jules-César Janssen, a French astronomer, noticed a yellow line in the sun's spectrum while studying a total solar eclipse in 1868. Sir Norman Lockyer, an English astronomer, realized that this line, with a wavelength of 587.49 nanometers, could not be produced by any element known at the time. It was hypothesized that a new element on the sun was responsible for this mysterious yellow emission. This unknown element was named helium by Lockyer.

Was helium discovered in 1868?
Yes, and it was discovered (and later isolated) by separate, independent scientists. Helium was discovered by the French astronomer Pierre (Jules) Janssen during a total solar eclipse in Guntur, India, in 1868. The same spectral emission lines were noted by the English astronomer Norman Lockyer, also in 1868, who proposed the name "helium," after Helios, the Sun God of Greek mythology. In 1895 Sir William Ramsay separated helium from air in the laboratory; the same year this experiment was repeated independently by Per Theodor Cleve and Nils Langlet in Sweden.
What group of elements did sir William ramsay discover?
Sir William Ramsay discovered the periodic group of noble gases. That includes argon, neon, helium, krypton, xenon, radon, and ununoctium.
