    NITROGEN IS MORE IMPORTANT THAN YOU THINK

    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

    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.

    Quantum field theory: The most beautiful theory

    Quantum field theory: The most beautiful theory  Quantum field theory is a combination of quantum theory and field theory. It provides help in combining quantum mechanics, classical mechanics, and special relativity. Nature loves beauty. Like nature, science is also like a beautiful theory. The theory which gives answers to all the questions of nature. In the beginning, classical mechanics was the most beautiful theory because it could answer all phenomena of nature accurately. But as our technology improves we can deep dive into matter and energy. The logic of classical mechanics becomes unvaried and that is why we need another theory that can explain all the phenomena at the quantum level. Quantum mechanics was able to resolve all the questions of the quantum world and then now become the most beautiful theory of science. It explains many phenomena like  Quantum entanglement , quantum tunneling, and other such strange phenomena. But quantum mechanics also won't be able to ex...

    HALOGEN FAMILY: THE MOST REACTIVE FAMILY OF THE PERIODIC TABLE

    HALOGEN FAMILY: THE MOST REACTIVE FAMILY OF THE PERIODIC TABLE Introduction: The halogen family contains fluorine, chlorine, bromine, iodine, and astatine. These elements are know for their reactiveness. This family contains many reactive elements known including fluorine which is one of the most reactive non-metals in the periodic table.  We are starting to talk about this family and its unique properties which blow your mind.   So, let's start: Fluorine: Fluorine is a very reactive non-metal. It is because of the fact that it has higher charged nuclei which are not shielded by electrons. That is why it attracts other element's electrons and thus forms compounds with them. Properties of fluorine: There are the following properties of fluorine: 1. Fluorine as discussed earlier is extremely electronegative which means it attracts electrons of other elements. 2. Fluorine is a highly reactive element. 3. Fluorine is very toxic and causes many disorders in the bodies of anima...

    Nitrogen: Cool Element very Important for Life

     Nitrogen is a very useful and abundant element in the atmosphere. About 78% of the atmosphere is composed of nitrogen elements. Nitrogen is a quite chill and cool element. Joke about Nitrogen: A scientist took a selfie while he was drinking liquid nitrogen He was quoted as saying "It was the coolest shot I ever took" Properties of nitrogen : Molecular weight: 14.01g/mol Boiling point: -195.795 degrees c Melting point: -210 degrees c Density: 1.251g/L Appearance: Colourless gas(at room temperature and pressure), Colourless liquid and solid. Isotopes of Nitrogen: Nitrogen has two stable isotopes N-14 and N-15. N-14 is the most abundant element in the atmosphere at 99.6% and N-15 is about 0.4% of this atmosphere. Each isotope has its own use for scientific and engineering purposes. Nitrogen Cycle and Nitrogen Fixation: First, all games start with atmospheric nitrogen which is composed of about 78% of the total atmosphere. But there is a problem plants and animals can't use ...
