NITROGEN IS MORE IMPORTANT THAN YOU THINK INTRODUCTION: In this article, we discuss nitrogen its important properties, and some incidents that happened in the past with people and instruments that deal with nitrogen. So, let's start: LIQUID NITROGEN INCIDENT THAT KILLED THREE TECHNICIAN OF NASA: The First space shuttle mission was named STS-1, the first orbital mission of NASA. This mission is uniquely described in this article due to the incident in which three technicians died due to inhalation of excess nitrogen of nitrogen. IMPORTANCE OF NITROGEN: Nitrogen is a crucial element in the periodic table due to many important properties. Nitrogen is a non-toxic & colorless gas that occupies 78% of the atmosphere. HISTORY OF NITROGEN: In the past, scientists had different opinions about this gas. For example, some scientists think it was brunt air because no combination occur in the presence of this element. Some believe it is very toxic and has no life because the environment fil...

Helium: Strange Element in Universe :
Introduction:
Helium is the second most abundant element in this whole visible universe after hydrogen. It is also the second lightest element in this universe after hydrogen. It seems that helium loves to leave behind hydrogen.
But helium shows unique characteristics that make them very unique and important for humanity. For example, Helium is used as a cryogenic substance in super-conductors used in MRI machines and to make "Superfluid" which shows unique behaviors that can be used in future technology.
Helium is the second most abundant element in this universe as we discussed earlier but helium is very rare in this planet on which we live. Because it is lighter than air they fly up and are present in the upper atmosphere from where cosmic radiation from the sun breaks them.
Helium is a very strange element because it can't react with any other element in ordinary conditions ( room temperature and pressure). But in extraordinary conditions, Na2He might be formed at about 130GPa and 1500k condition. It is predicted to be transparent and insulted.
Helium in the periodic table:
Helium is present in the top right corner of the periodic table. In group 8 whose element has a special name "Noble Gases". These elements are the least reactive elements humanity has ever known. Its contain element " Neon, Argon, Krypton, Xenon, Radon and Helium".
Rareness of Helium:
Helium is very rare on planet Earth. Because of think atmosphere helium can't stay and fly off into the upper atmosphere. That's why we can't store them?
So, the question arises from where this helium we use comes from? This question is nice. And the answer is that we mine them. Yes, you read right to mine them from underground. Helium present in the atmosphere is due to the radioactive decay of heavy elements. During the mining of natural gas, helium also comes out. So, in this way, we mine helium.
Helium isotopes
Isotopes have the atom which has the same atomic number but different mass numbers. Helium has 9 isotope He-2, He-3, He-4, He-5, He-6, He-7, He-8 and He-9. Which has its own properties and uses.
Helium superfluid:
Helium is a very strange compound as it does not freeze in a solid. At very low temperatures very near to absolute temperature helium became superfluid. Superfluid strange phase in which liquid has very low viscosity and also very high conductivity much higher than copper and gold.
Properties of helium:
1. It is lighter than air.
2. It is the second most abundant element in the universe.
3. It is an inert element that can't react with another element.
4. It has a very low melting point (-272.2 degrees Celsius) and boiling point (-268.928 degrees Celsius).
Uses of Helium:
1. The major use of helium is to full ballon.
2. Helium is also used as cryogenic material in many technologies in superconductors, MRI machines, in maglev trains.
3. Helium used to form superfluid used to study quantum level effect in liquid.
Conclusion:
Helium is a very important and rare gas. In technology, it has several uses and as technology grows we need more helium. That is why we as humans must find resources of helium to fulfill this requirement.
In my opinion, humans use helium and develop technology according to this. As its resources on Earth are very limited. But in-universe helium is a lot.
