Classify cach substance as an atomic element, molecular element, … WebIonic solids tend to have high melting points ("high" generally being higher than metallic but lower than covalent). Because the electrons in ionic solids are localized (in the ions) these solids tend to be stiff and brittle like covalent solids. As solids they do not conduct electricity (again because of the localize electrons).

WebA broad classification of solids in terms of their mechanical behavior would characterize them as brittle or ductile. While there is no doubt that ultimately this behavior is due to processes at the atomistic level, the link between these processes and their macroscopic manifestation is difficult to establish. WebIn their solid-state, non-metals tend to be brittle. Therefore, they lack the malleability and ductility exhibited by metals. Ductility is the property of the material to be stretched into wires but non-metals are not ductile except for carbon, as carbon fibres find uses in a wide variety of industries including sports and music equipment.
