Transition metals generally have high densities due to their metallic bonding. This type of bonding involves delocalisation of electrons within a "sea" of electrons surrounding positively charged metal ions. The close packing of these ions in the crystal lattice, combined with the strong electrostatic attraction between the ions and the delocalised electrons, results in a high density. The relatively small size of the metal ions also contributes to efficient packing.
- Metallic Bonding: Delocalisation of electrons.
- Close Packing: Efficient arrangement of ions in the crystal lattice.
- Strong Electrostatic Attraction: Between positive ions and the electron sea.
- Small Ionic Radii: Facilitates efficient packing.
