![]() When this layer is removed, the observations are more reliable. This is because its protective aluminium oxide layer makes it appear to be less reactive than it really is. Note that aluminium can be difficult to place in the correct position in the reactivity series during these experiments. The quicker the fizzing, the more reactive the metal. The speed at which hydrogen bubbles are produced tells us how reactive a metal is with acid. The tables show how the elements react with water and dilute acids: Element Observations of the way that these elements react with water, acids and steam enable us to put them into this series. For example: P eople S ay L ittle C hildren M ake A Z ebra I ll C onstantly S niffing G iraffes. The reactivity series of metalsĪ good way to remember the order of a reactivity series of metals is to use the first letter of each one to make up a silly sentence. More reactive metals have a greater tendency to lose electrons and form positive ions. Perhaps there are other benefits in that they encourage a playfulness with the subject.In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom. I think as a prompt they are fine, once pupils become more competent then they will leave them behind or use them as an occasional check. But some will struggle to do that.- Kristy Turner MaDo mnemonics work? ![]() I think it is better for pupils to make their own mnemonics and many people have replied with mnemonics designed by pupils not themselves. One of my students came up with one to remember the reactivity series that went "Pete Saw Carl's Mum In Lidl Cleaning Some Goo" MASH - Metal + Acid -> Salt + Hydrogen is a fave. (Methyl Ethyl Propyl Butyl)- Jason Burch MaDo you get your students to invent Mnemonics? Silverman MaDon’t monkey around with naming compounds Polite spotted leopard can meet affectionate zebra into tender loving care single girls please- Robert Brooks MaPractice your periodic tableĭon't think I've seen this one before: I remember the Al-Si-P-S-Cl row of elements as "Al sips chlorine".- Scott K. ♥️ □- Amy Szerminska MaRemember your reactivity series I also saw "Nick the Camel." in the replies. I prefer LEO goes GER to OIL RIG because it is clear electrons are what is lost/gained. SOAC a GERC (soak a jerk) makes me laugh Strongest Oxidizing Agent at the Cathode Gains Electrons and is Reduced at the Cathode.

Here are a few crackers for remembering some of the subject’s tricky details. ![]() A flurry of nifty aide-memoires were tweeted back. This week, Kristy Turner asked for your favourite chemistry mnemonics.
