Free movement of electrons can give the elements capability of electrical conductivity. The elements that are capable of conducting electricity are the elements that contain free moving delocalized electrons. An electric field within the metal triggers the movement of the electrons, if an electric ...

Why does graphene conduct electricity? Why is graphene more useful than carbon nanotubes? What are some uses for graphene? Why is graphene elastic? Why does graphene have high thermal conductivity? Why are carbon nanotubes used in thin film transistors?
Why do metals conduct heat so well?The electrons in metal are delocalised electrons and are free moving electrons so when they gain energy (heat) they vibrate more quickly and can move around, this means that they can pass on the energy more quickly.Which metals conduct the best?
To explain why ionic solids conduct electricity in the molten state but not in the solid state, we can break down the reasoning into several steps:1. Understanding Ionic Solids: Ionic solids are composed of positively and n
In recent years, the most significant gas and electricity price rises and cuts have been in reaction to changes in Ofgem’senergy price cap, which is reviewed and updated four times a year. But how can a cap change the prices suppliers are allowed to charge?
