Copper is formed by metallic bonds. This is because it is formed by a strong attraction between the closely packed positive metal ions and because these are surrounded by delocalised electrons to form outer shells. Due to this, we can also deduce that its structure is a Giant Metallic Lattice, meaning that it has a high melting and boiling point, conducts electricity and is insoluble.
Bromine formed by covalent bonds in between two bromine atoms, since bromine is a diatomic element. Each bromine atom shares one electron with each other, in order to complete their outer shell. Its structure is Simple Covalent Lattice, meaning that its melting and boiling point are low. Due to the weak forces of attraction between the molecules. b)i) E ii) C iii) F iv) B
2. Ferr- examples: Ferrell, Ferredoxin, Ferromagnetically, Ferrocene, Ferret, Ferrous, Ferric, Ferrocyanide.
The prefix “Ferr-“means that something contains iron.
-phile examples: Amphiphile, Paedophile, Electrophile, Nucleaphile, Hydrophile.
The suffix “-phile” means that there is an attraction to something. For example if chlorine is hydrophile (hydro means water or liquid), it means that it has a tendency to interact with water or dissolve in it.
