Nitrogen
A colorless nonmetallic element of atomic number 7 tasteless and odorless comprising four fifths of the atmosphere by volume in the form of molecular nitrogen N2 It is chemically very inert in the free state and as such is incapable of supporting life hence the name azote still used by French chemists but it forms many important compounds such as ammonia nitric acid the cyanides etc and is a constituent of all organized living tissues animal or vegetable Symbol N Atomic weight 14007 It was formerly regarded as a permanent noncondensible gas but was liquefied in 1877 by Cailletet of Paris and Pictet of Geneva and boils at 1958 deg C at atmospheric pressure Liquid nitrogen is used as a refrigerant to store delicate materials such as bacteria cells and other biological materials...

Helium
An inert monoatomic gaseous element occurring in the atmosphere of the sun and stars and in small quantities in the earths atmosphere in several minerals and in certain mineral waters It is obtained from natural gas in industrial quantities Symbol He atomic number 2 at wt 40026 C12011 Helium was first detected spectroscopically in the sun by Lockyer in 1868 it was first prepared by Ramsay in 1895 Helium has a density of 198 compared with hydrogen and is more difficult to liquefy than the latter Chemically it is an inert noble gas belonging to the argon group and cannot be made to form compounds The helium nucleus is the charged particle which constitutes alpha rays and helium is therefore formed as a decomposition product of certain radioactive substances such as radium The normal helium nucleus has two protons and two neutrons but an isotope with only one neutron is also observed in atmospheric helium at an abundance of 0013 Liquid helium has a boiling point of 2689deg C at atmospheri...
