  2. Atomic orbital - Wikipedia

    en.wikipedia.org/wiki/Atomic_orbital

    Four of the five d orbitals for n = 3 look similar, each with four pear-shaped lobes, each lobe tangent at right angles to two others, and the centers of all four lying in one plane. Three of these planes are the xy-, xz-, and yz-planes—the lobes are between the pairs of primary axes—and the fourth has the center along the x and y axes ...

  3. Delta bond - Wikipedia

    en.wikipedia.org/wiki/Delta_bond

    Formation of a δ bond by the overlap of two d orbitals 3D model of a boundary surface of a δ bond in Mo 2. In chemistry, a delta bond (δ bond) is a covalent chemical bond, in which four lobes of an atomic orbital on one atom overlap four lobes of an atomic orbital on another atom.

  4. Azimuthal quantum number - Wikipedia

    en.wikipedia.org/wiki/Azimuthal_quantum_number

    Three dumbbell-shaped polar-aligned orbitals; one lobe on each pole of the x, y, and z axes (on both + and − axes). 2 d: diffuse 10 Nine dumbbells and one doughnut, or "Unique shape #1" (see this picture of spherical harmonics, third row center). 3 f: fundamental 14 "Unique shape #2" (see this picture of spherical harmonics, bottom row center ...

  5. Square planar molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Square_planar_molecular...

    Representative d-orbital splitting diagrams for square planar complexes featuring σ-donor (left) and σ+π-donor (right) ligands. A general d-orbital splitting diagram for square planar (D 4h) transition metal complexes can be derived from the general octahedral (O h) splitting diagram, in which the d z 2 and the d x 2 −y 2 orbitals are degenerate and higher in energy than the degenerate ...

  6. Block (periodic table) - Wikipedia

    en.wikipedia.org/wiki/Block_(periodic_table)

    The d-orbitals (four shaped as four-leaf clovers, ... Of the f-orbitals, six have six lobes each, and the seventh looks like a dumbbell with a donut with two rings ...

  7. Molecular orbital diagram - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital_diagram

    The three dumbbell-shaped p-orbitals have equal energy and are oriented mutually perpendicularly (or orthogonally). The p-orbitals oriented in the z-direction (p z) can overlap end-on forming a bonding (symmetrical) σ orbital and an antibonding σ* molecular orbital. In contrast to the sigma 1s MO's, the σ 2p has some non-bonding electron ...

  8. Molecular orbital - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital

    A MO with δ symmetry results from the interaction of two atomic d xy or d x 2-y 2 orbitals. Because these molecular orbitals involve low-energy d atomic orbitals, they are seen in transition-metal complexes. A δ bonding orbital has two nodal planes containing the internuclear axis, and a δ* antibonding orbital also has a third nodal plane ...

  9. Trigonal prismatic molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Trigonal_prismatic...

    In chemistry, the trigonal prismatic molecular geometry describes the shape of compounds where six atoms, groups of atoms, or ligands are arranged around a central atom, defining the vertices of a triangular prism. The structure commonly occurs for d 0, d 1 and d 2 transition metal complexes with covalently-bound ligands and small charge ...
