Why do metals giant covalent structures not conduct electricity?
Metals have a sea of delocalized electrons that can move freely throughout the structure, allowing them to conduct electricity. In contrast, giant covalent structures like diamond and silicon have electrons localized in strong covalent bonds, making them insulators and unable to conduct electricity.
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 solid depends on electron sharing to hold it together and does not conduct electricity?
A covalent solid depends on electron sharing to hold it together, forming a network of covalent bonds between atoms. Since electrons are involved in forming strong covalent bonds, these solids do not have free-moving electrons and do not conduct electricity. Diamond and quartz are examples of covalent solids.
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.
Does argon have a giant covalent structure?
No, argon does not have a giant covalent structure. Argon is a noble gas that exists as individual atoms rather than forming covalent bonds with other atoms to create a giant structure.
Why do metals giant covalent structures not conduct electricity?

In contrast, giant covalent structures like diamond and silicon have electrons localized in strong covalent bonds, making them insulators and unable to conduct electricity.
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.

Why do giant convalent substances not conduct electricity?
Giant covalent substances do not conduct electricity because they lack free-moving charged particles. In these materials, atoms are held together by strong covalent bonds in a rigid lattice structure, which does not allow for the movement of electrons. While some covalent compounds may contain polar bonds, the absence of mobile ions or delocalized electrons means that they cannot carry an electric current. Consequently, these substances are typically insulators rather than conductors.

Since electrons are involved in forming strong covalent bonds, these solids do not have free-moving electrons and do not conduct electricity. Diamond and quartz are examples of covalent solids.
Why are covalent bonds poor conductors?
A covalent molecule is just the sharing of an electron and therefore there are no charges present (unlike an ionic compound that contains anions and cations joined through forces of attraction) so it cannot conduct electricity
What are the charateristics of a covalent bond?
In a covalent bond electrons are shared between the atoms being bonded. Compounds containing covalent bonds are molecular, tend to have a low boiling and melting point, and they do not conduct electricity. This is because the intermolecular forces are weak , van der Waals forces. Nite that giant covalent molecules are in fact high melting.
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.

No, argon does not have a giant covalent structure. Argon is a noble gas that exists as individual atoms rather than forming covalent bonds with other atoms to create a giant structure.
When atoms join by covalent bonds they form?
giant molecoule structures
What is a physical property of a giant covalent structure?
