We can make this reaction happen quicker by burning the metal. Created: Nov 11, 2011. Sneaky! Activity Series The relative reactivity of metals can be used to organize them into an activity series. It helps us to predict that particular metal can displace another metal from a compound or not. Khan Academy is a 501(c)(3) nonprofit organization. Reactive metals can also displace less reactive ones from solid metal oxides. Within each group, the metal lower down the group is more reactive. Interestingly, carbon can behave like a metal. This means they do not easily take part in chemical reactions. Explore why some metals are more reactive than other in terms of their ability to form a positive ion. Reactivity Series of Metals pupil worksheet. For example, because aluminium is more reactive than iron, it can displace iron from iron(III) oxide. Construct an activtiy series of metals. Metal + oxygen → metal oxide (a) Metal undergoes oxidation to form positive ions. If you're seeing this message, it means we're having trouble loading external resources on our website.
