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...
HALOGEN FAMILY: THE MOST REACTIVE FAMILY OF THE PERIODIC TABLE Introduction: The halogen family contains fluorine, chlorine, bromine, iodine, and astatine. These elements are know for their reactiveness. This family contains many reactive elements known including fluorine which is one of the most reactive non-metals in the periodic table. We are starting to talk about this family and its unique properties which blow your mind. So, let's start: Fluorine: Fluorine is a very reactive non-metal. It is because of the fact that it has higher charged nuclei which are not shielded by electrons. That is why it attracts other element's electrons and thus forms compounds with them. Properties of fluorine: There are the following properties of fluorine: 1. Fluorine as discussed earlier is extremely electronegative which means it attracts electrons of other elements. 2. Fluorine is a highly reactive element. 3. Fluorine is very toxic and causes many disorders in the bodies of anima...
