REACTIVITY OF CARBON SERIES
Which is an example of a reactivity series of metals?Ī reactivity series of metals could include any elements. Except for lead, all of the carbon family elements exist as different forms or allotropes. The elements tend to form covalent compounds, though tin and lead also form ionic compounds. Overall, the carbon family elements are stable and tend to be fairly unreactive. The carbon family elements have widely variable physical and chemical properties. What are the properties of the carbon family? It’s not lustrous, it is not malleable, it does not conduct electricity (however, it’s allotrope, graphite can due to vast electron de-localization within carbon layers. Carbon is included because this helps to explain what happens in the extraction of iron in a blast furnace. “Carbon and hydrogen are often included in the reactivity series even though they are non-metals. Why are carbon and hydrogen in the reactivity series? Aluminium is used for aeroplanes because of its low density. Electrolysis uses electricity to separate the metal from the other elements in the compound – learn more about electrolysis here. What elements are more reactive than carbon?Īluminium is more reactive than carbon so it must be extracted from ores containing aluminium oxide using this method. Note that zinc and iron can be displaced from their oxides using carbon but not using hydrogen. Non-metals in the reactivity series It is useful to place carbon and hydrogen into the reactivity series because these elements can be used to extract metals. Why is carbon present in reactivity series? This works because carbon is more reactive than lead, so carbon can reduce the lead oxide to lead. The lead oxide is then heated with coke (carbon) in a blast furnace to cause a displacement reaction which produces lead and carbon dioxide. It is useful to place carbon and hydrogen into the reactivity series because these elements can be used to extract metals. On the other hand, lead atom loses electrons with difficulty to form positive ions, so lead metal is less reactive. Such metals which can lose electrons easily to form positive ions when reacted with other substances, are reactive metals. When metals react, they lose electrons to form positive ions. Why some metal are more reactive and other less reactive? Carbon is less reactive than aluminium and magnesium. Therefore, carbon can reduce copper(II) oxide and zinc oxide to their respective metals. Where does carbon stand in the reactivity series?Ĭarbon is above copper but below magnesium in the reactivity series.ĭiscussion: Carbon is more reactive than copper and zinc. Reduction with carbon is often used to extract these metals and requires less energy to reduce them to extract the metal. Less reactive metals, such as iron, form less stable oxides and other compounds. Very reactive metals, such as aluminium, form stable oxides and other compounds. Why is carbon used instead of a more reactive metal? At standard temperature and pressure, it resists oxidation it does not react with sulfuric acid, hydrochloric acid, chlorine, or any alkali metals. 7 Which is an example of a reactivity series of metals?ĭespite the fact that it is present in a vast number of compounds, carbon is weakly reactive compared to other elements under normal conditions.6 Why are carbon and hydrogen in the reactivity series?.5 What elements are more reactive than carbon?.
