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.

Are solids malleable?
Solids are typically not malleable. Malleability is a property of materials to be shaped or deformed by applying pressure, which is commonly found in metals such as gold or silver.
If both molecular solids and network solids contain covalent bonds why do network solids have such higher melting points than molecular solids?
Network solids have a three-dimensional structure with strong covalent bonds throughout, leading to a higher melting point compared to molecular solids which have weaker intermolecular forces. In network solids, a larger amount of energy is required to break the extensive network of covalent bonds, resulting in a higher melting point.
What are covalent-network solids?
Covalent-network solids are substances in which atoms are bonded together by strong covalent bonds in an extended network structure. This results in materials with high melting points, hardness, and electrical insulating properties. Examples include diamond and silicon carbide.
Which attractive forces stabilize network solids?
In network solids, attractive forces like covalent bonds, ionic bonds, and metallic bonds stabilize the structure. These strong bonds between atoms or ions help maintain the rigid and three-dimensional network structure of network solids.
What is the state of matter for lanthanides?
Lanthanides exist as solids at room temperature and pressure. They have metallic properties and are typically soft, malleable, and ductile.
What bonds are malleable solids in?
a malleable solid is dense
Are solids malleable?

What are examples of malleable solids?
A Rubber and Chewing Gum
Sentence for malleable?
able to be bent or otherwise changed in shape

Does helium have malleabillity?
Malleability is a property of solids and not gases. Helium is a gas and hence is not malleable.
What can a solid do that has plasticity?
Hi. Some solids are malleable, such as gold, and move quite readily. Some solids, such as diamond, do not move very much at all.
Which type of solids have a very ordered arangment of particles?
Network solids.
What is a solid that consists of crystals?
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.
How do you test for the melting point?
The melting point is determined with special devices. See this link.
How do shape and volume defer with solids liquids and gasses?
both are fixed (unless acted upon by outside forces) in a solid; volume is fixed but shape is malleable in a liquid; and both are malleable in a gas.
What are covalent-network solids?
Covalent-network solids are substances in which atoms are bonded together by strong covalent bonds in an extended network structure. This results in materials with high melting points, hardness, and electrical insulating properties. Examples include diamond and silicon carbide.
