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...
Beryllium used in Space Shutters and in web space telescope Beryllium is the fourth element in the periodic table. It is the second lightest metal after lithium. It is a shiny grey metal that has a very high melting point. It is an element also used in web space telescopes. So let's start this article and explore this element: Discoverer of Beryllium: Berylium is an element discovered by French chemist "Lewis Nicholas Bachmann" in 1798. This metal was isolated by two chemists "Fredrich Wohlor" from Germany and " Antoine Bussie" from french in 1828. This element originally known as "Glucinium" is derived from the Greek word "Glykys" which means "sweet in taste". In 1957 the metal was officially named "Beryllium" after the Greek word "Beryllos" means "Mineral Barrel". Berlium is very reactive that why it can't be found in its pure form. Beryllium is obtained from the minerals "beryl, be...
