With reference to Asian Infrastructure Investment Bank (AIIB), consider the following statements AIIB has more than 80 member nations. There are three isotopes of hydrogen namely, protium 1H1, deuterium 1H2 or D and lastly tritium 1H3 or T. The isotopes are different because of the different number of neutrons present in them. It has a half-life of 23 yoctoseconds. They have different physical properties because of the large variations in mass. Three naturally existing isotopes of hydrogen are tritium, deuterium, and protium. A green bond is a fixed-income instrument designed specifically to support specific climate-related or environmental projects.

From UPSC perspective, the following things are important : Prelims level : NHEM. Its compounds are used in chemical analysis and solvents for hydrogen 1. Required fields are marked *. The nucleus of hydrogen 2 is termed as deuteron. In the universe, hydrogen is the most abundant element (70% of the total mass) and it is also the principal element of the solar atmosphere. Hydrogen-5 is a highly unstable isotope of hydrogen. It is radioactive, it decays into helium 3 through beta decay. It comprises 6 neutrons and 1 proton. There is no neutron in hydrogen, one in deuterium, and two neutrons in tritium. Out of these three isotopes of hydrogen. Because its nucleus has only one proton, it is called protium. As the electronic configuration of isotopes is the same, they all have similar chemical properties. UPSC: UPSC Civil Service Prelims 2021 exam is scheduled for June 27.
