Brief description: hydrogen is the lightest element. It is by far the most abundant element in the universe and makes up about about 90% of the universe by weight. Hydrogen as water (H2O) is absolutely essential to life and it is present in all organic compounds. Hydrogen is the lightest gas. Hydrogen gas was used in lighter-than-air balloons for transport but is far too dangerous because of the fire risk (Hindenburg). It burns in air to form only water as waste product and if hydrogen could be made on sufficient scale from other than fossil fuels then there might be a possibility of a hydrogen economy.
Hydrogen is an odorless, colorless gas that has the number 1 on the Periodic Table of elements.
Hydrogen is a gas. H2 is the description of its molecular structure (2 hydrogen atoms bound together).
No. You might say a description for the formula H2O is two hydrogen atoms bonded to an oxygen atom.
There are actually seven elements that fit that description - hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine.
Compounds that contain carbon-hydrogen bonding are collectively termed organic compounds. These are simply compounds that would contain hydrogen and carbon elements.
hydrogen and hydrogen gas are same hydrogen is gas
Hydrogen is a gas. H2 is the description of its molecular structure (2 hydrogen atoms bound together).
the simplest element. Hydrogen is a gas, a non-metal, it is the lightest element.
It is an alkali metal
No. You might say a description for the formula H2O is two hydrogen atoms bonded to an oxygen atom.
2 atoms of hydrogen and one atom of oxygen.
The letter h in pH scale stands for Hydrogen. The proper description for the name ph. is potential of Hydrogen.
Molecules made of carbon and hydrogen are various and diffuse. The best description is that they are hydrocarbons and they burn well.
Glucose lose electrons and hydrogen to form Carbon dioxide.
The planet Saturn does not have a solid surface. Saturn is almost entirely made up of gases, hydrogen and helium.
Sounds like a description of amino acids.
That's a reasonable description of a "hydrocarbon"
Overlap of each hydrogen 1s orbital with four sp3 hybridized orbitals yielding four sigma bonds.
