1. Explain why a metal conducts electricity when solid or molten but an ionic compound conducts only when molten and not when solid. 2. Explain why the melting point increases from top to bottom going down group 7 (the halogens). 3. a) Which type of
electrolysis of molten lead bromide products electrode …
The electricity must flow through electrodes dipped into the electrolyte to complete the electrical circuit with the battery. Electrolysis can only happen when the circuit is complete, and an electrical current (electricity) is flowing, then the products of electrolysing molten lead(II) bromide are released on the electrode surfaces where they can be collected.

Conducts electricity Mg yes no yes I 2 no yes no Use your knowledge of structure and bonding to explain the results of the tests. Using your knowledge of structure and bonding, explain why, although both graphite and copper are good conductors of
Graphite is a non - metal. But still it conducts ele …
Graphite is a non metal but still can conduct electricity because of the delocalised (free) electrons in its structure. This is because each carbon atom in graphite is bonded to only three other carbon atoms and its fourth valence electron is free.

It is thought that nanoparticles can pass through the skin and travel around the body more easily than normal-sized particles. It is also thought that nanoparticles might be toxic to some types of cell, such as skin, bone, brain and liver cells. (a) Explain why
physical chemistry - Graphite: Thermal and electrical …
These delocalized pi electrons are the reason why graphite can conduct electricity along the planes, where as diamond cannot due to the lack of delocalized electrons. Diamond is a better conductor of heat because the transfer of heat takes place through adjacent atoms transferring their vibrational energy and diamond has a very close knit network of atoms where as graphite does not.
Once this is done I give them a 6 mark question: explain why graphite conducts electricity but diamond does not, which they self assess. Very pacey lesson with excellent outcomes. Read more

organic chemistry - Why does graphite conduct …
In graphite structure, two of them make two single (sigma) bonds while the other pair form a double bond (consists of one sigma and one pi bond). Electron that forms pi bond is freer to travel between atoms compared to the others and is theoretically associated with all adjacent atoms (imagine the 3d structure of graphite) rather than a single atom.
1. Look at the diagram. It shows a structure of carbon.
Explain, using ideas about structure and bonding, why silicon dioxide has a high melting point.  (b). Graphite is another allotrope of carbon. Graphite is used in pencil leads. Look at the structure of graphite. Explain, using ideas about structure and bonding
