Covalent solids have strong covalent bonds between atoms, giving them a very high melting and boiling point. They are typically hard and have low electrical conductivity due to the localized nature of electrons in the covalent bonds. Examples include diamond and quartz.

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.


What usually has a lower melting points than the ionic solids?

Covalent solids and molecular solids typically have lower melting points than ionic solids. This is because the intermolecular forces holding covalent and molecular solids together are generally weaker than the electrostatic forces binding ionic solids, resulting in lower energy requirements for melting.


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 usually has lower melting points than ionic solids?

Molecular solids


What are the properties of a covalent compounds?

Covalent compounds are formed when atoms share electrons to achieve a full outer shell. They typically have lower melting and boiling points compared to ionic compounds, and are often gases, liquids, or soft solids at room temperature. Covalent compounds do not conduct electricity in their pure form.

Properties of solids?

Particles of solids are packed tightly together and can't move. They don't change shape unless damaged.


What have a lower melting points than ionic solids?

Covalent solids generally have lower melting points than ionic solids. This is because covalent solids are made up of discrete molecules held together by relatively weak intermolecular forces, whereas ionic solids are made up of ions held together by strong electrostatic forces. The weaker intermolecular forces in covalent solids require less energy to overcome, resulting in a lower melting point.
