Facts Which you probably don't know about Helium
Here we got some 10 fascinating facts about the element Helium. So let's start:-
Q.1:- Can Helium be made by man?
A:- There is no chemical way of manufacturing helium
Q.2:- Is helium gas is flammable?
A:- Even it is 1/4th part of Sun, Helium is not flammable,
Q.3:- How bad is helium for you?
A:- The good news is, breathing helium does not kill brain cells. The bad news is that breathing helium can, in fact, kill you — but not because of the helium, rather because of the lack of oxygen when you inhale the helium.
Q.4:- How was helium named?
A:- The image is of the sun because helium gets its name from 'helios', the Greek word for the sun. Helium was detected in the sun by its spectral lines many years before it was found on Earth. A colorless, odorless gas that is totally unreactive.
Q.5:- Where was helium first discovered on Earth?
A:- In space:-Scientific discoveries. 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. The line was detected by French astronomer Jules Janssen during a total solar eclipse in Guntur, India.
On Earth:-In 1895, Sir William Ramsey found helium on Earth when he experimented with combining the uraninite material cleveite with mineral acids.
Q.6:- Is Helium an antigravitational gas?
A:- yes Helium is antigravitational, that's why helium-filled balloon goes up and up.
Q.7:-Shooting stars?
A:-Space technology is very delicate and precise, Liquid fuels of NASA shuttles are very volatile and they contain corrosive materials that could destroy the spacecraft. Helium gas is used to prevent this from happening as it’s light and non-flammable.
Q.8: Cooling MRI's?
A:- At its low boiling point of -269°C, helium is ideal to cool down the MRI magnets safely and effectively.
Q.9:- Which state? at absolute zero?
A:- It is the only known element that will remain in a liquid state at a temperature of absolute zero under normal pressure.
Q.10:-Isotopes?
A:-There are eight isotopes of helium, but only two are stable and are abundant.
Bonus time (Rapid Facts):-
- Helium is present in our Earth's atmosphere at approximately 0.0005% by volume, which is considered very rare
- It is the only known element that will remain at a liquid state at a temperature of absolute zero under normal pressure.
- The United States National Helium Reserve controls 30% of the world's current helium supply, and the Reserve is expected to run out of helium by 2018.
