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...
OXYGEN FAMILY: AND EXTREME IMPORTANCE OF THEM Radioactive Polonium Introduction: Air is important to survive life on Earth but mainly oxygen. Similarly, water is important for life and contains hydrogen and oxygen. Like all this, several elements play an important role in our life. Well, a discussion about all of them required to much time. So, in this article, we are taking an overview Oxygen Family. Let's Start: 1. Oxygen: Well, oxygen is the most popular element. Everyone knows about it and its purposes. Well, in chemistry oxygen is infamous for its oxidation properties which are useful but also cause many difficulties due to this property most metals like iron and zinc, etc., are oxidase which causes many problems. Properties of Oxygen: 1. Oxygen is colorless, odorless, tasteless gas at STP (Standard temperature and pressure). 2. Oxygen is a very reactive element. 3. While oxygen is useful for life but high concentration of oxygen is very toxic. Likewise, its allotropy o...
