Why transition metals are good conductor of electricity?
- 9 years agoFavourite answer
Transition metals have giant metallic structure (with a 'sea of delocalised electrons' and metal cations). These delocalised electrons are not bound to a specific metal atom and are free to move around within the lattice structure, hence are able to act as electrical carriers which helps to explain transition metals' high electrical conductivity.
On a side note, transition metals have even higher electrical conductivity than their counterparts in group 1 and 2, because they have even more valance electrons (Additional electrons in d subshell but that's considered extra so you don't really need to worry about it) in their lattice structures to act as free electrical carriers.

They form solids with a "sea of electrons" where every electron is delocalized (delocalized means that it is not associated with a particular nucleus). This allows the electrons to respond to a slight voltage and flow away from a negative charge and toward a positive one.
