Why are ionic compounds formed when a metal reacts with a non-metal?
  • One or more electrons are transferred from the metal to the non-metal
  • One or more electrons are transferred from the non-metal to the metal
  • All of the electrons are transferred from the metal to the non-metal
  • They share a pair of electrons
What would you see if you added potassium to water?
  • An explosion
  • The metal fizzes and burns with a purple flame.
  • The metal fizzes, forms a molten ball and moves around the surface of the water
  • The metal fizzes and moves around but doesn't melt
Which of the following would be produced when lithium carbonate reacts with nitric acid?
  • Hydrogen
  • Water
  • Lithium nitrate
  • Carbon dioxide
If you drop a piece of cleaned magnesium ribbon into a solution of silver nitrate, the magnesium becomes coated with a grey substance. What is the explanation for this?
  • Magnesium is more reactive than silver and displaces the silver
  • Magnesium is less reactive than silver and displaces the silver
  • The magnesium reacts with the nitrate and is coated in magnesium nitrate
  • Silver in silver nitrate is actually more reactive than magnesuim ribbon so the magnesium corrodes
