WebSep 12, 2024 · Graphite Diamond Silicon dioxide (SiO 2) Silicon carbide Boron carbide Transition elements, etc Metallic Crystalline solid Metallic solids are composed of atoms joined together to form large sheets. These atoms are placed in the form of layers, one above the other joined by a metallic bond. WebDec 15, 2024 · Metallic solids are crystalline solids formed by atoms of the same metallic element. The bonding electrons are delocalised over the space of the crystal and have the freedom to move from one end to the other. All these bonding electrons of the metal atoms constitute a sea of electrons. bisbee bus route
