The first known sample of helium was identified by the French astronomer Pierre Janssen in 1868 during a solar eclipse. He discovered a new spectral line in sunlight that did not correspond to any known element, leading him to propose the existence of a new element, which he named "helium" after the Greek word for the sun, "helios." This was later confirmed by the British chemist Sir William Ramsay in 1895 when he isolated helium on Earth.
What else can I help you with?
Is oxygen gas also known for helium?
Oxygen is not known as helium. But a mixture of oxygen and helium is used in the oxygen cylinder for underwater diving.
How was the existence of helium confirmed in the sun?
Through the spectrum. Signatures of an element was found that was not known on Earth. Some years later, it was also found on Earth. Hence the name, "helium".Through the spectrum.

How do you get the gas known as helium?
Helium is obtained as a byproduct of methane extraction.
How much atoms does helium have?
Atomic Mass of helium is 4.002602
How was helium identified on the sun with a spectroscope?
Every element, when heated, sends out light with characteristic spectral lines. These same lines are also absorbed when the element is present in an atmosphere between a light source and the observer. When studying spectral lines of the sun some lines were noted that were not known on earth, from which we concluded that there must be an inknown new element. Which was subsequently found on earth.

Is helium known as inert?
Yes, helium is an inert gas.
What is the significance of the helium lamp spectrum in the study of atomic emission spectroscopy?
The helium lamp spectrum is important in atomic emission spectroscopy because it provides a reference for identifying and calibrating the wavelengths of light emitted by other elements. By comparing the emission lines of unknown samples to the known lines of helium, scientists can determine the elemental composition of a sample.

What are the chemical properties of helium?
Helium is inert. There are no known compounds. It has no chemical properties.
What is the first member of the noble gases and the second most abundent element in the universe?
Helium is the first member and the most abundent element in the known universe
What compound does helium exist in?
There are no known compounds of helium. Helium is a noble gas , it has a full valence shell with 2 electrons, (1s2).
What are you if you are gas with two protons in your nucleus?
