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...
Lithium is an extraordinary Element Lithium was discovered by Swedish chemist Johan A. August in 1817. Named from the Greek word lithos, it means stone. It is the third-highest element in nature. Appearance is soft-sliver grey. Lithium is the topic of today's discussion. So, let's start: As you all know lithium is from its major application in batteries which are used in several devices. Lithium is the third lightest element known to humans. Lithium in the periodic table: Lithium is present in alklia family. The Alkalia family has the special property of forming alkalis with water. Lithium has an atomic number of 3 its mass number is 6.914u and it has a very low density in the periodic table. Lithium is the lightest metal known to man. That is why is alloy majorly used in the aerospace industry. Lithium mineral : As lithium is very reactive it cannot be found in nature in its pure form. Its major minerals are "lepidolite, petalite, and spodumene".From this we human...
