Reactivity of group 7 metals
Did you know?
WebThe halogens, group 7, are an important group of elements both chemically and socially. They are unusual in that they are coloured and diatomic. They also have an order of reactivity that is the opposite of the metals in groups 1 and 2. … WebThis shows electronegativity decreasing (as reactivity increases) down Group 1 and it also decreasing (as reactivity decreases) down Group 7. ... "It is used to summarize information about the reactions of metals with acids and water, double displacement reactions and the extraction of metals from their ores." $\endgroup$ – Gaurang Tandon.
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.
