In the year 1868, there was a solar eclipse in India which made a In the year 1868, there was a solar eclipse in India which made a French Astronomer named Pierre Jules Janssen, who was curious French Astronomer named Pierre Jules Janssen, who was curious to find out about the Chromospheres around the sun and that to find out about the Chromospheres around the sun and that was the first time that anyone did it. Soon he discovered and was the first time that anyone did it. Soon he discovered and studied about the striped yellow line. After that, he succeeded studied about the striped yellow line. After that, he succeeded on proving that the yellow stripe was a new element. Two English on proving that the yellow stripe was a new element. Two English Astronomer named Sir Joseph Norman Lockyer and Eduard Astronomer named Sir Joseph Norman Lockyer and Eduard Franklard agreed with Janssen’s results that the element was not Franklard agreed with Janssen’s results that the element was not earthly. So they named the new element ‘Helium’ after the Greek earthly. So they named the new element ‘Helium’ after the Greek word ‘Helios’ meaning the sun. word ‘Helios’ meaning the sun.

When the year 1895 came, Helium wasn’t really that productive until When the year 1895 came, Helium wasn’t really that productive until this man named Sir William Ramsey who continued on the this man named Sir William Ramsey who continued on the Helium experiment, and founded the uses for it that made it Helium experiment, and founded the uses for it that made it popular until today.

Helium FactsHelium Facts

Helium is an element that is the second lightest element but doesn’t Helium is an element that is the second lightest element but doesn’t form any compound. Helium is odorless, colorless, tasteless, non-form any compound. Helium is odorless, colorless, tasteless, non-toxic and insipid. With the periodic toxic and insipid. With the periodic symbol of ‘He’ symbol of ‘He’ and the and the atomic number of 2atomic number of 2, it is a gas that is lighter than air and isn’t , it is a gas that is lighter than air and isn’t flammable. At about flammable. At about 4 Kelvin (-269 Celsius)4 Kelvin (-269 Celsius), Helium becomes , Helium becomes liquid, and when Helium becomes liquid, it has many uses for it, liquid, and when Helium becomes liquid, it has many uses for it, and even when Helium is in gas form, it can also be used for and even when Helium is in gas form, it can also be used for many things. Helium has the lowest of the many things. Helium has the lowest of the melting point for -melting point for -272 Celsius272 Celsius, and , and boiling point of -268.9 Celsiusboiling point of -268.9 Celsius. It has a .

Effects on the EnvironmentEffects on the Environment

Helium has no hazardous effect with the environment because Helium has no hazardous effect with the environment because it is a harmless gas and it can mostly effect with health. it is a harmless gas and it can mostly effect with health. However, even though if helium did effect the environment, However, even though if helium did effect the environment, it wouldn’t be as effective because there won’t even be it wouldn’t be as effective because there won’t even be enough helium for it is a very light molecule that would run enough helium for it is a very light molecule that would run out as it goes to outer space. out as it goes to outer space.

When Helium has no effect on the environment it can effect the When Helium has no effect on the environment it can effect the voice. Helium is actually founded as a component of a voice. Helium is actually founded as a component of a natural gas, like from the United States for it is a radioactive natural gas, like from the United States for it is a radioactive decay of minerals underground, so it wouldn’t be a harm decay of minerals underground, so it wouldn’t be a harm with the environment.with the environment.
