What are the factors of metallic bond strength?
- Charge density of cation (charge/radius)
larger magnitude of charge density, stronger attraction between +ion and delocalised e-, stronger metallic bond - Number of delocalised e-
larger no. of delocalised e-, more extensive interactions between +ion and delocalised e-, stronger metallic bond
