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...
Carbon: An Element of Life Carbon: An Element of Life Carbon is an element of life. We, humans, use carbon so much that we can't think of living without carbon and its compounds. Carbon is an element formed in stars during a process called "Nucleosynthesis". This is the process by which smaller nuclei fuse together to form larger nuclei. Carbon is an element of extreme importance in today's world not just in the fuel sector but also in the pharmaceutical industry as well in factories and large industries. Carbon is an element of the periodic table that has an atomic number of 6 and a mass number is 12.011u it has 6 electrons of which 4 are its valence electrons. It has a valency of 4. That is why it forms large compounds that are necessary for life and this property of carbon is known as "catenation". Allotropy of carbon: Carbon is a very important compound that has several allotropy but in this article, we discuss only its two most important allotropy. For...
