  2. Unpaired electron - Wikipedia

    en.wikipedia.org/wiki/Unpaired_electron

    The ions with the largest number of unpaired electrons are Gd 3+ and Cm 3+ with seven unpaired electrons. An unpaired electron has a magnetic dipole moment, while an electron pair has no dipole moment because the two electrons have opposite spins so their magnetic dipole fields are in opposite directions and cancel. Thus an atom with unpaired ...

  3. Ligand field theory - Wikipedia

    en.wikipedia.org/wiki/Ligand_field_theory

    In complexes of metals with these d-electron configurations, the non-bonding and anti-bonding molecular orbitals can be filled in two ways: one in which as many electrons as possible are put in the non-bonding orbitals before filling the anti-bonding orbitals, and one in which as many unpaired electrons as possible are put in. The former case ...

  4. VSEPR theory - Wikipedia

    en.wikipedia.org/wiki/VSEPR_theory

    Shows location of unpaired electrons, bonded atoms, and bond angles. The bond angle for water is 104.5°. Valence shell electron pair repulsion ( VSEPR ) theory ( / ˈ v ɛ s p ər , v ə ˈ s ɛ p ər / VESP -ər , [ 1 ] : 410 və- SEP -ər [ 2 ] ) is a model used in chemistry to predict the geometry of individual molecules from the number of ...

  5. Lone pair - Wikipedia

    en.wikipedia.org/wiki/Lone_pair

    The pairs often exhibit a negative polar character with their high charge density and are located closer to the atomic nucleus on average compared to the bonding pair of electrons. The presence of a lone pair decreases the bond angle between the bonding pair of electrons, due to their high electric charge, which causes great repulsion between ...

  6. Electronic effect - Wikipedia

    en.wikipedia.org/wiki/Electronic_effect

    Electronic spin state at it simplest describes the number of unpaired electrons in a molecule. Most molecules including the proteins, carbohydrates, and lipids that make up the majority of life have no unpaired electrons even when charged. Such molecules are called singlet molecules, since their paired electrons have only one spin state.

    Nitrome's Ice Breaker is an entirely different game and it's just as awesome. Ice Breaker mixes strategic thinking with the need for a steady, quick cutting hand. And if you plan on saving all ...

  8. Transition metal dinitrogen complex - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_di...

    Transition metal complexes of N 2 have been studied since 1965 when the first complex was reported by Allen and Senoff. [3] This diamagnetic complex, [Ru(NH 3) 5 (N 2)] 2+, was synthesized from hydrazine hydrate and ruthenium trichloride and consists of a [Ru(NH 3) 5] 2+ centre attached to one end of N 2.
