Document Summary
Metallic solids: shinny, silver, lustrous, and re ective, good conductivity of heat and electricity, can range in hardness from soft to hard, workable (metals can be made into different shapes without shattering, low ionization energies and electronegativities. Metals have continuous, very compact, closely packed, crystalline structures. **the more delocalized valence electrons the stronger the bond. Metallic bonds are typically weaker than covalent and ionic bonds. The individual bond strength of a metallic bond can differ depending on different factors: as the amount of protons in a bonded metal increase, the more force of attraction they have on delocalized electrons. This is due to the increase of the ionization of the metal"s nucleus. Therefore, the more protons a metal has, the stronger the metallic bond is: the more valence electrons present in a bonded metal, the more delocalized electrons that are available for bonding. This weakens the attraction between the delocalized electrons and the atoms nucleus.
