Reactivity of group 7 metals
Webreaction products, and the relevant binary phase diagrams, is surveyed. Information is included on the magnetic and electrical behaviour of some alloys, especially those with the higher platinum contents. Although the alloying behaviour of the platinum group metals with the Group IB ele- ments copper, silver and gold has been studied WebGroup 14 = 4 valence electrons – this is a special group because they can either lose 4 or gain 4 for a full shell. Whether they lose or gain 4 depends on what they are reacting with. Still a reactive group however it is difficult to lose/gain 4 electrons, so this group is less reactive than groups 1,2 & 17 Group 17 = 7 valence electrons.
