2. Metallic bonding - Wikipedia

   en.wikipedia.org/wiki/Metallic_bonding

   Metallic bonding is a type of chemical bonding that arises from the electrostatic attractive force between conduction electrons (in the form of an electron cloud of delocalized electrons) and positively charged metal ions.

3. Metal–metal bond - Wikipedia

   en.wikipedia.org/wiki/Metal–metal_bond

   In many compounds, metal-metal bonds are accompanied by bridging ligands.In those cases, it is difficult to state unequivocably that the metal-metal bond is the cohesive force binding the two metals together.

4. Cyclopentadienyl complex - Wikipedia

   en.wikipedia.org/wiki/Cyclopentadienyl_complex

   Zirconocene dichloride, a cyclopentadienyl complex. A cyclopentadienyl complex is a coordination complex of a metal and cyclopentadienyl groups (C 5 H − 5, abbreviated as Cp −).

5. J-B Weld - Wikipedia

   en.wikipedia.org/wiki/J-B_Weld

   A package of J-B Weld, showing "hardener" (red tube) and "steel" (black tube of resin): equal amounts are squeezed from both tubes and mixed. The J-B Weld Company is an international company that produces epoxy products.

6. Glass-to-metal seal - Wikipedia

   en.wikipedia.org/wiki/Glass-to-metal_seal

   Uranium glass used as lead-in seals in a vacuum capacitor. Glass-to-metal seals are a type of mechanical seal which joins glass and metal surfaces. They are very important elements in the construction of vacuum tubes, electric discharge tubes, incandescent light bulbs, glass-encapsulated semiconductor diodes, reed switches, glass windows in metal cases, and metal or ceramic packages of ...

7. Mercury polycations - Wikipedia

   en.wikipedia.org/wiki/Mercury_polycations

   Structural details of [Hg 4] 2+ in [Hg 4](AsF 6) 2.Distances in picometers. [1]Mercury polycations are polyatomic cations that contain only mercury atoms. The best known example is the Hg 2+

8. Metal–ligand multiple bond - Wikipedia

   en.wikipedia.org/wiki/Metal–ligand_multiple_bond

   In organometallic chemistry, a metal–ligand multiple bond describes the interaction of certain ligands with a metal with a bond order greater than one. [1] Coordination complexes featuring multiply bonded ligands are of both scholarly and practical interest.

9. Pi backbonding - Wikipedia

   en.wikipedia.org/wiki/Pi_backbonding

   σ bonding from electrons in alkene's HOMO to metal center d-orbital. π backbonding from electrons in metal center d-orbital to alkene's LUMO. As in metal–carbonyls, electrons are partially transferred from a d-orbital of the metal to antibonding molecular orbitals of the alkenes and alkynes.
