Oxygen

Great Discoveries Of Chemistry

  • Oxygen

    Oxygen
    Oxygen is one of the more popular elements due to its key role in supporting life.
  • Atoms Combine Into Molecules

    Atoms Combine Into Molecules
    The combined equal volumes of different gasses measured the reaction the gasses often produced twice the volume.
  • Electrons Forming Chemical Bonds

    A chemical bond is a lasting attraction between atoms that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between atoms with opposite charges, or through the sharing of electrons as in the covalent bonds.
  • Electricity Transforms Chemicals

    Electricity transformations are critical today to expand the technology of human civilization.
  • Synthesis Of Urea

    The Synthesis of Urea was created by Friedrich Wöhler in an attempt to synthesize ammonium cyanate.
  • Periodic Table Of Elements

    Periodic Table Of Elements
    Dimitri Mendeleev started the development of the periodic table, arranging chemical elements by atomic mass.He wanted to discover the best way to teach his class about the disclosed elements. He predicted the discovery of other elements, and left spaces open in his periodic table for them.
  • Atomic Theory

    Atomic Theory
    John Dalton stated that elements like hydrogen, oxygen, and carbon are combined with definite and constant proportions.
  • Electrons For Chemical Bonds

    Strong chemical bonds are the intermolecular forces which hold atoms together in molecules. A strong chemical bond is formed from the transfer or sharing of electrons between atomic centers and relies on the electrostatic attraction between the protons in nuclei and the electrons in the orbitals.
  • Fullerne

    A fullerene is a molecule of carbon in the form of a hollow sphere, ellipsoid, tube, and many other shapes. Spherical fullerenes, also referred to as Buckminsterfullerenes or buckyballs, resemble the balls used in association football
  • Atoms Have Signatures Of Light

    The signatures of lightdetermined to be caused by the absorption of light by electrons in moving between atomic orbitals when it passed through atoms, with each atom having a characteristic signature due to the quantum nature of these orbitals.
