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...
Alkaline Earth Metals: And Its Unique Properties Introduction: The chemistry is wonderful not only for the reason that I liked it but also because it organizes things very well. As to read the title of this article you know that I am talking about the second group of the periodic table. Yah! Periodic table. Predictability of Periodic table: In groups mainly things of different elements are predictable which is very surprising. That is why Dmitri Mendeleev before discovering the element described their properties and it was quite surprising that he was right. So, think you thought that chemistry is difficult subject known to humans. But How Dmitri Mendeleev predict things that means if you have some little knowledge about periodic tables and some other basic concept of chemistry similar to physics things are predictable I mean in classical physics. In this article we study about following points : 1. What is an alkaline earth metal? 2. Alkaline Earth Metals Proper...
