Where is the the rest of the information for this structure and bonding topic
On the structure and bonding mind map
Why do simple Covalent structures have low melting boiling points
Because they have weak intermolecular forces, meaning not much energy is needed to overcome the forces of attraction.
Do giant covalent structures have low or high melting and boiling points. And why?
Have high melting and boiling points because a lot of energy is required to break the high intermolecular forces of attraction.
Why is diamond so hard?
Very hard because 4 out of 4 carbon atoms are covalently bonded.
Why does diamond not conduct electricity
4 out of 4 carbon atoms are covalently bonded which mean there are no free electrons to carry the charge
Can a giant ionic lattice conduct electricity
yes but only when molten or dissolved
