Hydrogen and Oxygen have many properties in common, but they have a lot of differences as well. Both are gases, both are colorless, both are odorless. They both differ from each other in the following regard:
Hydrogen has one unpaired electron whereas oxygen has two unpaired electrons.
Hydrogen can form only one covalent bond whereas oxygen can form two covalent bonds.
The most common isotope in hydrogen has no neutron in its nucleus whereas there are 8 neutrons in most common isotope of oxygen.
Atomic mass of oxygen is far greater than that of hydrogen. Hydrogen has an atomic mass of 1.00794u where as oxygen has an atomic mass of 15.999u
The main difference between Hydrogen and Oxygen is that Hydrogen has no neutrons in its most stable isotope whereas Oxygen has 8 neutrons in its most stable isotope. And oxygen has greater mass.
Helium is extracted in a few places in the world, namely USA, Algeria, Russia and Qatar. Helium is abundant in space, where it's produced as a product of the fusion reaction inside stars such as the sun.
