I assume you mean, how did Helium get its name as it has never been known as anything else.
It was named after HELIOS the ancient Greeks' god of the sun, as it was first identified during spectral analysis of the sun's light during a solar eclipse in 1868,
Origin / Meaning of the name Helium
The name originates from the Greek word 'helios' meaning sun.
Helios the greek word that means sun. Discovered by Sir william ramsey
Helium is a chemical element which is found in the gaseous state and you will find it very light and colourless. The distinct characteristic of the gas is that it does not burn and is mostly used in balloons and also to freeze food.
The reason behind the nomenclature of the element is that it was first noticed in the spectrum of the chromosphere of the sun. As the sun in known as 'Helios' in the Greek language the scientists who discovered it named it as Helium.
Helium is considered as the second most abundant element present in our universe and it is second only to hydrogen. The Big Bang theory of the formation of the universe says that the major part of the element was formed during Big bang nucleosynthesis and only within one to three minutes after the occurrence of the Big Bang.
What I think from the web site is that helium is a chemical element that it found in the sun and earth too it contain hydrogen.
Yes air have weight to it like helium a ballon has helium and it floats without air we can not breathe and we will not have any ballons.
Helium basically is a colourless, odourless, tasteless, chemical element. It is one of the most unreactive noble gases, hence which makes it one of the slightest chemically-active elements based on the periodic table.
The boiling point as well as the heating point of helium is the lowest amid all the elements, apart from in intense environment, it subsist only as a gas. At heat levels close to total zero, it is a superfluid, at virtually frictionless stage of substance with extraordinary properties.
Helium is the second lightest element after Hydrogen; it is also the second most copious element present in the universe. It was first perceived in the year 1869 by French astronomer Pierre Janssen. He described it as a strange yellow spectral line cross in the light of solar eclipse. Helium was later on individually distinguished as a new element later on in the year 1869 by English astronomer Norman Lockyear.
It is a unreactive noble gas that is in balloons for example
