Hydrogen is a gas, nonmetal, considered by IUPAC a member of the group I of the Periodic Table of elements.
1.aluminum 2.helium 3.hydrogen
Hydrogen can participate in various chemical reactions, such as combustion with oxygen to form water, reaction with halogens to form hydrogen halides, and reaction with metals to form metal hydrides. Hydrogen can also participate in hydrogenation reactions where it adds to unsaturated compounds, such as in the hydrogenation of alkenes to alkanes.
The letter H is the chemical symbol for the element hydrogen.
The chemical formula for hydrogen sulphide is H2S. (Compounds have chemical formulas; only chemical elements have chemical symbols.)
pH refers to the chemical potential of hydrogen.
The sun does not "burn" a specific chemical, rather it goes through a process called nuclear fusion where hydrogen atoms fuse together to form helium, releasing a tremendous amount of energy in the form of light and heat.
The chemical formula for Hydrogen gas is H2
Hydrogen is neither a chemical or physical property...it is a chemical element.
Hydrogen is a chemical property because it is a pure substance and it cannot be broken down into simpler substances by physical means. It is the simplest and most abundant chemical element in the universe.
The chemical formula of carbon is C and the chemical formula of hydrogen is H.
The chemical formula for Hydrogen gas is H2
The Chemical Formula for Hydrogen Chloride is HCl.
