    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...

    HYDRIDES OF ALKALI METALS

    HYDRIDES OF ALKALI METALS:

    Introduction:

    Well, in our previous articles, we talked about Alkali Metals now we talk about its compounds which are their hydrides. Hydrides are the type of binary compound of hydrogen with some other elements for example, in this case, we are talking about Hydrides of Alkali Metal.

    Properties of Alkali Metal Hydrides:

    Some Common Properties of Alkali Metal Hydrides:

    1. Formation of Alkali Metal Hydrides:

    The formation of alkali metal hydrides occurs by a direct reaction between alkali metal and hydrogen. But need temperatures which are given below:

    LiH           700-800 degrees Celsius

    NaH           200-400 degrees Celsius

    KH             300-500 degrees Celsius

    RuH            400-600 degrees Celsius

    CsH           500-700 degrees Celsius

    Well, you do not need to learn the temperature at which the reaction starts occurring. There is a pattern except for LiH all others have some unique pattern. For example, NaH needs 200-400 degrees Celsius, and KH needs 300 (100+) - 500 (100+) degree Celsius. All others except LiH follow the same pattern.

    2. Formation of Ionic bond:

    There is a property that is common in all alkali metal hydrides which is the formation of ionic bonds. These compounds form ionic bonds and show characteristics which is common in ionic bonds strong ness, high melting and boiling point, and other such properties that are common in ionic compounds.

    3. Physical State:

    All the alkali metal hydrides exist in a solid state at room temperature and pressure.

    4. Solubility:

    Alkali metal hydrides are insoluble in non-polar solvents but soluble in water due to the process of hydrolysis. Hydrolysis is the reaction in which water is used for breaking big molecules into smaller ones.

    5. Reactivity:

    All the alkali metal hydrides are very highly reactive.

    Uses and Applications of Alkali Metal Hydrides:

    1. We all know the fuel of the future is hydrogen but its storage is a major problem. Here Alkali metal hydrides especially LiH are useful.

    2. These compounds are very important reduction agents.

    3. These alkali metal hydrides are useful as neutron shields and neutron absorbers (especially LiH).

    4. Alkali Metal Hydrides are useful drying agents.

    5. As you notice all the alkali metal hydrides are strong bases and that why useful in organic reactions in which an acid-base reaction is required.

    Conclusion:

    All the compounds are unique all their uses are also very specific. I think to wonder about that the knowledge of the periodic table is so amazing. These are five compounds that we know about in great depth with minimum work.

    That's all about the Hydrides of Alkali Metal. I hope you like it.

    BOSONS: AND ITS SECRET POWER IN NATURE

    BOSONS: AND ITS SECRET POWER IN NATURE  Introduction: Nuclear and particle physics, one of the most powerful branches of physics, deals with nuclear and particles present in atoms. In Nuclear and particle physics, they are the "Standard model of particle physics". In the standard model of particle physics, two divisions divide the particle into two categories known as "Bosons and fermions" . Fermions: Fermions are the particles that are responsible for the formation of all the ordinary matter in this universe. We discuss this in detail in the previous article. Fermions Bosons: Bosons are particles that are responsible for all the basic forces in this universe. Forces are of multiple types but for all the forces we humans know scientists select four forces and say that there are "Basic forces of universe". These are as follows: 1. Weak nuclear force 2. Strong nuclear force 3. Gravitational force 4. Electromagnetic force Particles of that force: These forc...

    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...

    Wave particles duality: History of Light

     Wave particle duality: History of Light Light is a wave. Oh! sorry particle. Oh! sorry sorry both. Light is a particle or wave you decide after reading this article and leaving your answer in the comment after reading this article. Light According to Newton: Newton which is very famous in classical mechanics. Classic mechanics without Newton is not possible. Imagine the equations of motion and laws of motion which are very useful to describe any motion of a machine or for satellites. Our current technology is based on the phenomena of classical mechanics. And this can't be ignored how useful classical mechanics are in our daily lives. Newton thought that light is a particle to prove this Newton gave his corpuscles theory. According to Newton's corpuscles theory, "light is a particle called corpuscles". This theory is instrumental in describing most of the phenomena of light. But in many cases it fails, for example, to describe phenomena such as interference and polar...
