9.2 Network Covalent, Ionic, and Metallic Solids

Explaining Metal Properties • Variable melting points – Melting point depends upon the strength of the bonds. This in turn generally depends upon the nuer of valence electrons. However, there is no simple correlation • High liquid temperature range – Vaporizing a metal requires the valence electrons to

Properties of Transition Metals VS Calcium

28.02.2011· Melting Point. Transition metals have high melting points due to their strong metallic bonding. Metallic bonding is defined by delocalization of valence electrons, leaving the metal ions to be eedded in a sea of delocalized electrons. More delocalized electrons, the stronger the metallic bonds.
