  2. Triatomic hydrogen - Wikipedia

    en.wikipedia.org/wiki/Triatomic_hydrogen

    Triatomic hydrogen or H 3 is an unstable triatomic molecule containing only hydrogen. Since this molecule contains only three atoms of hydrogen it is the simplest triatomic molecule [1] and it is relatively simple to numerically solve the quantum mechanics description of the particles. Being unstable the molecule breaks up in under a millionth ...

  3. Trihydrogen cation - Wikipedia

    en.wikipedia.org/wiki/Trihydrogen_cation

    The structure of H + 3 The MO diagram of the trihydrogen cation. The three hydrogen atoms in the molecule form an equilateral triangle, with a bond length of 0.90 Å on each side. The bonding among the atoms is a three-center two-electron bond, a delocalized resonance hybrid type of structure.

  4. Triatomic molecule - Wikipedia

    en.wikipedia.org/wiki/Triatomic_molecule

    Homonuclear triatomic molecules contain three of the same kind of atom. That molecule will be an allotrope of that element. Ozone, O 3 is an example of a triatomic molecule with all atoms the same. Triatomic hydrogen, H 3, is unstable and breaks up spontaneously.

  5. Molecular orbital diagram - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital_diagram

    A diatomic molecular orbital diagram is used to understand the bonding of a diatomic molecule. MO diagrams can be used to deduce magnetic properties of a molecule and how they change with ionization. They also give insight to the bond order of the molecule, how many bonds are shared between the two atoms. [12]

  6. H3 - Wikipedia

    en.wikipedia.org/wiki/H3

    Triatomic hydrogen (H 3), an unstable molecule; Trihydrogen cation (H + 3), one of the most abundant ions in the universe; Tritium (3 H), or hydrogen-3, an isotope of hydrogen; ATC code H03 Thyroid therapy, a subgroup of the Anatomical Therapeutic Chemical Classification System

  7. Walsh diagram - Wikipedia

    en.wikipedia.org/wiki/Walsh_diagram

    Walsh diagrams in conjunction with molecular orbital theory can also be used as a tool to predict reactivity. By generating a Walsh Diagram and then determining the HOMO/LUMO of that molecule, it can be determined how the molecule is likely to react. In the following example, the Lewis acidity of AH 3 molecules such as BH 3 and CH 3 + is predicted.

  8. Atomicity (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Atomicity_(chemistry)

    Atomicity is the total number of atoms present in a molecule of an element. For example, each molecule of oxygen (O 2) is composed of two oxygen atoms. Therefore, the atomicity of oxygen is 2. [1] In older contexts, atomicity is sometimes equivalent to valency. Some authors also use the term to refer to the maximum number of valencies observed ...

  9. Bent molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Bent_molecular_geometry

    Water (H 2 O) is an example of a bent molecule, as well as its analogues. The bond angle between the two hydrogen atoms is approximately 104.45°. [ 1 ] Nonlinear geometry is commonly observed for other triatomic molecules and ions containing only main group elements, prominent examples being nitrogen dioxide (NO 2 ), sulfur dichloride (SCl 2 ...
