S2.3 The metallic model
This section describes the bonding in metals, what the strength of the metallic bond depends upon and how this affects their melting point, electrical conductivity, thermal conductivity and malleability. At Standard Level the metals are confined to the s and p block elements. This is extended to include the d block metals for the Additional Higher Level material. @font-face {font-family:"Cambria Math"; panose-1:2 4 5...
