  2. Bohr model of the chemical bond - Wikipedia

    en.wikipedia.org/wiki/Bohr_model_of_the_chemical...

    The Bohr model of the chemical bond took into account the Coulomb repulsion - the electrons in the ring are at the maximum distance from each other. [2] Thus, according to this model, the methane molecule is a regular tetrahedron, in which center the carbon nucleus locates, and in the corners - the nucleus of hydrogen. The chemical bond between ...

  3. Chlorine dioxide - Wikipedia

    en.wikipedia.org/wiki/Chlorine_dioxide

    The structure according to Pauling's General Chemistry Vapor-liquid equilibrium above an aqueous solution of chlorine dioxide at various temperatures. The molecule ClO 2 has an odd number of valence electrons, and therefore, it is a paramagnetic radical.

  4. Bohr model - Wikipedia

    en.wikipedia.org/wiki/Bohr_model

    The Bohr model of the hydrogen atom (Z = 1) or a hydrogen-like ion (Z > 1), where the negatively charged electron confined to an atomic shell encircles a small, positively charged atomic nucleus and where an electron jumps between orbits, is accompanied by an emitted or absorbed amount of electromagnetic energy (hν). [1]

  5. Atomic radii of the elements (data page) - Wikipedia

    en.wikipedia.org/wiki/Atomic_radii_of_the...

    Just as atomic units are given in terms of the atomic mass unit (approximately the proton mass), the physically appropriate unit of length here is the Bohr radius, which is the radius of a hydrogen atom. The Bohr radius is consequently known as the "atomic unit of length". It is often denoted by a 0 and is approximately 53 pm. Hence, the values ...

  6. Chlorine oxide - Wikipedia

    en.wikipedia.org/wiki/Chlorine_oxide

    Chlorine and oxygen can bond in a number of ways: chlorine monoxide radical, ClO•, chlorine (II) oxide radical; chloroperoxyl radical, ClOO•, chlorine (II) peroxide radical; chlorine dioxide, ClO 2, chlorine (IV) oxide; chlorine trioxide radical, ClO 3 •, chlorine (VI) oxide radical; chlorine tetroxide radical, ClO 4 •, chlorine (VII ...

  7. Chlorine - Wikipedia

    en.wikipedia.org/wiki/Chlorine

    The Cl–Cl distance is 198 pm (close to the gaseous Cl–Cl distance of 199 pm) and the Cl···Cl distance between molecules is 332 pm within a layer and 382 pm between layers (compare the van der Waals radius of chlorine, 180 pm). This structure means that chlorine is a very poor conductor of electricity, and indeed its conductivity is so ...

  8. History of atomic theory - Wikipedia

    en.wikipedia.org/wiki/History_of_atomic_theory

    In a trilogy of papers Bohr described and applied his model to derive the Balmer series of lines in the atomic spectrum of hydrogen and the related spectrum of He +. [37]: 197 He also used he model to describe the structure of the periodic table and aspects of chemical bonding. Together these results lead to Bohr's model being widely accepted ...

  9. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
