Covalent network solids are generally not malleable. They have crystal structures that lack obvious glide planes and the covalent bonds are difficult to break and remake. This is a contrast with the metals where many of the crystal structures have glide planes and metallic bonds are relatively easy to break and remake.
Some solids, particularly certain metals, are malleable, but many are not.
Network Solids are atomic solids that contain strong directional covalent bonds to form a solid that might be best viewed as a giant molecule.

They are hard, shiny and found on the left and middle of the Periodic Table. They are mostly found as solids.

a malleable solid is dense

able to be bent or otherwise changed in shape
Malleability is a property of solids and not gases. Helium is a gas and hence is not malleable.
Hi. Some solids are malleable, such as gold, and move quite readily. Some solids, such as diamond, do not move very much at all.
The particles in quids are more malleable/ easily shaped, since they aren't as close together as particles in solids.
Network solids.
The melting point is determined with special devices. See this link.
Network Solids are atomic solids that contain strong directional covalent bonds to form a solid that might be best viewed as a giant molecule.
Network solids, or network atomic solids, are large crystals with covalent bonds holding the atoms together. Gemstones including diamonds and rubies are network solids. Crystalline solids have a constituent arranged in ordered patterns and include amethyst quartz.
At room temperature most metals are solids. They are this way in order to be malleable so they can be worked.
