Wanted For:

Hydrogen is wanted for being the most abundant element in the universe. Hydrogen is what stars use for 'fuel', and the same process the sun uses for fuel is being researched here on Earth as a possible energy source. Hydrogen is also important for some commercial reasons, like it can be combined with as liquid hydrogen and liquid oxygen to serve as great rocket fuel. It is also important because hydrogen makes up 90% of the visible universe.

Rocket Fuel

In this picture, liquid hydrogen and liquid oxygen serve as rocket fuel for the space shuttle to use for its propulsion into space.

Description and Aliases

Hydrogen is without color, smell, taste, and non toxic, you could say it is a very boring element. It's atomic number is 1, and atomic mass 1.00798 or 1.008 (simplified), it is a Non-Metal and is highly combustible, which is why it can be used for rocket fuel, etc. Other names for hydrogen can be protium, deuterium, and tritium.

Arrest Details and Last Seen

Hydrogen is under non-metals in the periodic table, and is mostly found in the water of our oceans. The element was first seen in 1671 when a scientist named Robert Doyle found that the reaction between iron fillings and dilute acids produced a gas, and later in 1766 Henry Cavendish found the same thing, and was the first scientist to see hydrogen as a "discrete substance". Only in 1781 did Antoine Lavoisier name the element hydrogen after the Greek hydro for water and genes for creator. Robert Boyle was an Anglo-Irish natural philosopher, chemist, physicist, and inventor form Ireland. He is most known for Boyle's Law

Known Associates

Hydrogen combines with other elements to create:

  • Ammonia
  • Water
  • Methane
  • Table Sugar


Hydrogen might not be very dangerous in its normal state, but it can be HIGHLY flammable/combustible, so DO NOT play around with fire close to hydrogen!

Fun Facts

  • 10% of an organism's weight is hydrogen.
  • Liquid hydrogen is the lightest of all liquids.
  • Hydrogen is the single element that can exist with a single neutron.
  • Hydrogen's most abundant isotope does not have any neutrons.
