Answer
In metallic crystals, the outermost electrons of the metal atoms become delocalised. This means that they are not bound to any specific atom and can move freely throughout the metallic structure.
Step 2
Electrons free to move

Answer
This free movement of delocalised electrons allows metallic crystals to conduct electricity effectively, as these electrons can carry charge throughout the material when a potential difference is applied.
