    Who Found Hydrogen and How

    • Henry Cavendish discovered hydrogen in 1766 in London.
    • Cavendish was a prominent natural philosopher, scientist, chemist, and physicist.
    • Cavendish's experiment helped calculate the gravitational constant.
    • Antoine Lavoisier later reproduced Cavendish's experiment and gave the element its name.

    How was Hydrogen Found by Cavendish?

    • Cavendish described the density of inflammable air and its reaction to form water on combustion.
    • This was documented in the paper "On Factitious Airs."
    • Lavoisier later refined these findings.

    • Hydrogen's position in the periodic table is described and its electronic configuration is explained.

    Hydrogen Facts

    • Hydrogen is the most abundant element in the universe (75% of the known mass).
    • Stars primarily fuse hydrogen to produce helium during their lifespan.
    • Hydrogen is crucial for numerous molecules and biological processes.

    Basic Properties of Hydrogen Element

    • Atomic hydrogen is the simplest and lightest element.
    • It consists of one proton, and one electron, and no neutrons.
    • Hydrogen has three isotopes (protium, deuterium, and tritium).
    • The isotopes have subtle differences in mass but similar electronic and chemical properties.

    Basics about the Hydrogen Molecule

    • Hydrogen atoms combine to form an H₂ molecule.
    • This molecule has a strong covalent bond.
    • The equilibrium bond length is 0.74 Å.
    • Bond dissociation energy is 4.52 eV (436 kJ/mol).
    • The molecule is colorless, though various “colors” are discussed in reference materials.

    Basics about the Hydrogen Molecule (Isotopes)

    • Hydrogen exists as ortho- and para-hydrogen isomers.
    • At standard temperature and pressure, H₂ gas is approximately 75% ortho and 25% para.
    • The ortho/para ratio decreases as temperature decreases.

    Basics about the Hydrogen Molecule (Reactions)

    • Hydrogen can react under certain conditions with various elements and molecules.
    • An example is the reaction with oxygen to produce water.
    • This process often occurs through a combustion reaction.

    Physical Properties of Hydrogen vs. Other Fuels

    • A comparison table of hydrogen's density, energy, and other physical properties with other fuels like natural gas, LNG and gasoline is presented.
