the constituent particles of metallic solids are +ve ions but it is a conductor of electricity why? |
Metallic Solids In these type of solids, the constituent particles are metal atoms. The interparticle forces in these solids are metallic bonds. In the metallic crystals the metal atoms occupy the fixed positions but their valence electrons are mobile. The close packed assembly of metal kernels (part of metal atom without valence electrons) remain immersed in the sea of mobile valence electrons. The attractive force between the kernels and mobile valence electrons is termed as metallic bond. Characteristics of Metallic Solids The common characteristics of metallic solids are as follows: They generally range from soft to very hard. They are malleable and ductile. They are good conductors of heat and electricity. They possess bright lustre. They have high melting and boiling points. They have moderate heats of fusion. |
