Metals are strong, shiny, good conductors of heat and electricity, can be shaped into wires, make a ringing sound when struck, and some are magnetic. Non-metals do not share these properties and are generally less reactive than metals. The document sorts common elements into metals and non-metals based on their properties and reactivity, with lithium, sodium, and potassium being the most reactive metals with water.

1. Properties of Metals

2. Learning objectives To be able to tell the difference between a metal and a non metal Be able to describe where metals and non metals are located on the periodic table

3. So what are the properties of a metal? Metals conduct Heat Metals conduct electricity Metals are strong Metals are shiny

4. Are there any more properties of metals? Metals make a dong sound when hit Metals can be shaped into wires Metals don’t melt easily Some metals are magnetic

5. What you are going to do Sort the element cards into metals and non metals. Draw a table into your exercise book with the sorted elements listed. Extension – Can you place the cards into order based on the reactivity with water? Try to say why the metals are in this order. Where are they on the periodic table Most Reactive Least Reactive Non Metals Metals

6. So what were the metals? Sodium Lithium Potassium Silver Gold Copper Helium Argon Fluorine Neon Chlorine Bromine Non Metals Metals

7. Order of reactivity Least Reactive with water Most Reactive with water Copper Gold Silver Sodium Lithium Potassium
