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...
HYDRIDES OF ALKALI METALS: Introduction: Well, in our previous articles, we talked about Alkali M etals now we talk about its compounds which are their hydrides. Hydrides are the type of binary compound of hydrogen with some other elements for example, in this case, we are talking about Hydrides of Alkali Metal. Properties of Alkali Metal Hydrides: Some Common Properties of Alkali Metal Hydrides: 1. Formation of Alkali Metal Hydrides: The formation of alkali metal hydrides occurs by a direct reaction between alkali metal and hydrogen. But need temperatures which are given below: LiH 700-800 degrees Celsius NaH 200-400 degrees Celsius KH 300-500 degrees Celsius RuH 400-600 degrees Celsius CsH 500-700 degrees Celsius Well, you do not n...
