Giant covalent structures have high melting and boiling points due to the strong covalent bonds throughout the structure. They are also hard and insoluble in water because of their strong network structure. Examples include diamond, graphite, and silicon dioxide.
Giant covalent structures include diamond and graphite, which are all made of carbon, and silicon(IV) oxide.
Properties:
- Covalent bonds link atoms throughout the network structure
- Is solid at room conditions
- The melting and boiling points are very high
- THey are usually hard (except for graphite)
- They are insoluble in water or non-aqueous solutions (heptane)
- Non-conductors of electricity (except graphite)
That's it. Hope it helps all those who use the internet to find infotmation about science!

Do giant covalent structures contain charged ions?
No, giant covalent structures do not contain charged ions. They are formed by a network of covalent bonds between atoms, where electrons are shared between them rather than transferred to form charged ions. Examples of giant covalent structures include diamond and graphite.
Why are giant covalent structures non conductors of electricity?
Giant covalent structures, such as diamond and silicon dioxide, have a strong network of covalent bonds that hold their atoms together in a rigid structure. These bonds do not allow for the movement of electrons, which is necessary for conducting electricity. Therefore, giant covalent structures are non-conductors of electricity.
What is the boiling point of giant covalent?
Giant covalent structures, such as diamond and graphite, do not have a specific boiling point because their atoms are held together by strong covalent bonds that require high temperatures to break. These structures do not boil in the traditional sense like molecular substances but rather decompose or undergo phase transitions at extremely high temperatures.
What do giant covalent structures look like in a gas state?
Giant covalent structures do not exist in a gas state because they have strong covalent bonds that hold their structure together. In a gas state, molecules are moving freely and not in a fixed, rigid structure like giant covalent structures, such as diamond or graphite.
Does covalent structures have high or low boiling points?
Covalent structures generally have low boiling points compared to ionic or metallic structures. This is because covalent bonds are relatively weak compared to ionic or metallic bonds.

When atoms join by covalent bonds they form?
giant molecoule structures
Can giant covalent structures conduct electricity when molten?
Yes, giant covalent structures can conduct electricity when molten because the atoms are free to move and carry charge. This allows for the formation of a continuous pathway for the flow of electricity. Examples of giant covalent structures that can conduct electricity when molten include graphite and silicon.
What is the boiling point of giant covalent?
Giant covalent structures, such as diamond and graphite, do not have a specific boiling point because their atoms are held together by strong covalent bonds that require high temperatures to break.

What is (covalent) compound?
COVALENT
Why does silicon can form giant structures?
Silicon can form giant structures due to its ability to bond with other silicon atoms through covalent bonds, creating a strong and stable network structure. This continuous network of silicon atoms allows for the formation of giant structures such as silicon crystals or silicon-based materials.

Giant covalent structures do not exist in a gas state because they have strong covalent bonds that hold their structure together. In a gas state, molecules are moving freely and not in a fixed, rigid structure like giant covalent structures, such as diamond or graphite.
Does covalent structures have high or low boiling points?
Covalent structures generally have low boiling points compared to ionic or metallic structures. This is because covalent bonds are relatively weak compared to ionic or metallic bonds.
What following types of compound can form giant structures ionic covalent metal?
Ionic compounds can form giant structures, such as ionic lattices, due to the attraction between positively and negatively charged ions. Similarly, covalent compounds, like diamond or silicon dioxide, can form giant structures through the sharing of electrons between atoms. Metal compounds can also form giant structures, known as metallic lattices, due to the delocalization of electrons among metal atoms.
Two properties of compounds with giant ionic structures?
Sodium Chloride Magnesium Oxide
Is water a giant covalent structure?
No, water is not a giant covalent structure. Water molecules are held together by hydrogen bonds, which are much weaker than the covalent bonds typically found in giant covalent structures like diamond or graphite.
