No, because the molecules are neutral so therefore there are no charged particles to carry a current.

Why do metals giant covalent structures not conduct electricity?
Because there are no free electrons. However, graphite does conduct electricity as there are free electrons.
Why graphite is soft and greasy and good conductor of electricity?
Unlike most Giant Covalent Structures like diamond that form four covalent bonds, Graphite only forms 3, meaning it has a free electron meaning that graphite can conduct electricity.
What solid depends on electron sharing to hold it together and does not conduct electricity?
This would seem to be looking for the answer covalent substances. However, there are two types of covalent substance: molecular (e.g. sulfur) and giant covalent (e.g. diamond). Electron sharing certainly holds giant covalent lattices together, but in a molecular substance the electron sharing is only within the molecule, and the forces which hold the molecules together to make a solid are rather weaker. They may be van der Waals forces, dipole-dipole attractions, or hydrogen bonds.
Which compound has a high melting point covalent and non metals?
A possible compound would be silicon dioxide with giant covalent structure and strong covalent bonds.
Is water a giant covalent structure?
No. Water is molecular, H2O. The molecules "clump together" due to hydrogen bonding, but these bonds are much weaker than the covalent O-H bonds

Can giant covalent structures conduct electricity when molten?
Some do- for example molten silicon conducts like ametal when molten.
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.
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
When atoms join by covalent bonds they form?
giant molecoule structures
Why does silicon can form giant structures?
Silicon (like carbon) can form covalent bonds, it forms a giant molecule with the diamond structure. Silicon dioxide is also a giant structure with polar covalent bonds. Silica reacts with basic oxides to form silicates- and these are generally giant structures, polar covalent bonds again, that form a very large proportion of the minerals in the earths crust.

What is (covalent) compound?
COVALENT
Which compound has a high melting point covalent and non metals?
A possible compound would be silicon dioxide with giant covalent structure and strong covalent bonds.
What kind of chemical bond do crystals have?
Ionic compunds which are crystalline- have ionic bonds. Giant covalent can also be crystalline e.g. diamond and silica- these have covalent bonds. Molecular compounds crystallise - these have covalent bonds and the crystals are held together by van der waals forces. and sometimes by hydrogen bonds.
Is water a giant covalent structure?
No. Water is molecular, H2O. The molecules "clump together" due to hydrogen bonding, but these bonds are much weaker than the covalent O-H bonds
