Hydroge is not a recognized term in geological or historical contexts. If you meant "Hydrogeology," it refers to the study of the distribution and movement of groundwater in the soil and rocks of the Earth's crust. This field encompasses various periods, primarily focusing on the present and recent geological history, but it also considers ancient aquifers and their formation over millions of years. If you meant something else, please clarify.
hydrogen? they have one proton
Helium is the lighter gas but hydrogen is very flammable
Hydro Gen is a shortened form of "Water maker", because when you burn it, you get H2O which is water.
An atom--being of Carbon, Hydroge, Nitrogen or Oxygen--is at the smallest structural level of an organism such as a moose. Give ideas
Sulfuric acid is probably derived from hydroge sulfide diffused in the cave during geologic times.
The chemical formula for hydrogen peroxide is H2O2. It is a simple compound composed of two hydrogen atoms and two oxygen atoms.
The atomic mass of an element is average of the number of protons in an atom plus the number of neutrons. For example, if you look at a periodic table of elements, Hydroge has the atomic mass of 1.0079.
The molecular formula for hexane is C6H14. Therefore, the greatest number of hydrogen atoms in hexane is 14.
after Jurrasic period it is the Cretaceous period
The balanced equation for the reaction of ammonia (NH3), oxygen (O2), and methane (CH4) to form hydrogen cyanide (HCN) and water (H2O) is: 4 NH3 + 3 O2 + CH4 → 2 HCN + 6 H2O

The period after the Devonian Period (416 to 359.2Ma) is the Carboniferous Period (359.2 to 299Ma).
