INTRODUCTION
Hydrogen is an important element with approximately 1% of the earth's crust . It is found free only in very small amounts about 0.01% in the atmosphere and in the volanic gases.It has the smallest atoms of any element.
Hydrogen atoms were among the first atoms to form in the early universe,it is found in large variety which are water,organic substance,crude oil and also essential components of all living matter.
