What are the properties of solids? Explain the properties of solids in terms of the molecules or atoms that compose them.
Solids have many different properties, including conductivity, malleability, density, hardness, and optical transmission, to name a few. Few properties of solid are discussed below,
Electrical and thermal conductivity
Heat, or thermal conductivity is closely related to electrical conductivity. Just as metals are good electrical conductors, you probably know from experience that they’re good at conducting heat too.
graphite sheets, they are relatively good at conducting heat and electricity. Metal conducts heat and electricity well because the bonds between atoms arenondirectional.very rigid.
Malleability and ductility
Two additional properties, malleability and ductility, follow trends similar to those for electrical and thermal conductivity. Malleability describes the ability to hammer a solid into a sheet without breaking it, and ductility refers to whether a solid can be stretched to form a wire. As you may have guessed, metals tend to be both malleable and ductile, largely due to the non-directionality of metallic bonds. In contrast, covalent and ionic bonds, which are directional and require specific geometries resulting in fixed three-dimensional lattice structures, make many other types of solids brittle so they break under force.
Another way to deform a solid is to melt it. A solid’s melting point depends on the strength of the interactions between its components: Stronger interactions mean a higher melting point. For molecular solids, melting means breaking the weak intermolecular forces (the forces between different molecules), not the strong covalent bonds that hold the individual molecules together, so a compound like sugar can be easily melted on your stovetop.
