Question Answer
Typical properties of metals - - Solid - Strong - Malleable - Conductor of heat and electricity - Shiny/ reflective - Sonorous - Ductile - High melting and boiling points.
Typical properties of a non - metal - - Usually liquid or gas - Non - rigid structure - Low density - Dull, not shiny - Low melting and boiling points
Alloy An alloy is a mixture of metals or a mixture of a metal and another element.
Metal + Water Metal hydroxide + hydrogen
OH Hydroxide
How many extra electrons does group one have? 1
How many extra electrons does group two have? 2
Metal + oxygen Metal oxide
Oxidation When a metal reacts with oxygen
What happens when metal is left in contact with air or water? Corrodes, for Iron it's called rust.
Preventing corrosion - - Plastic coating - Oil - Galvanising (Zinc coating) - Painting - Sacrificial protection (Using a more reactive metal over the one that needs to be saved from corrosion.)
Laboratory acids - Nitric Acid - Sulphuric Acid - Hydrochloric Acid
Nitric Acid HNO_3_
Sulphuric Acid H_2_SO_4_
Hydrochloric Acid HCL
Acids All acids are in liquid form and have hydrogen
How many extra electrons does hydrogen have - 1
How many extra electrons does nitrate have - -1
How many extra electrons does chloride have - -1
How many extra electrons does sulfate have - -2
Metal + Acid Salt + Hydrogen
Salt Salt is a compound made of a metal and non - metal.
Precipitate This means insoluble salt, so it slowly builds up as a solid.
Metal Carbonate has - 1 metal atom 1 carbon atom 3 oxygen atoms
Metal carbonate + acid Salt + water + carbon dioxide
Displacement reaction This is where one element is replace by another in a compound as its more reactive - E.g. Mg+ CuSO4 = Cu + MgSO4
More reactive metal + Less reactive metal compound = More reactive metal compound + Less reactive metal
More reactive metal compound + Less reactive metal = More reactive metal + Less reactive metal compound - No reaction
Metal hydroxide + Acid Salt + Water
Metal oxide + water This reactions produces an alkaline solution
Metal oxide + acid Neutralise themselves
Non - metal + oxide Non - metal oxide. E.g. Sulfur + Oxide = Sulfur dioxide. This is an acid.
Non - metal oxide + bases Non-metal oxides react with bases and neutralise them.
Non - metal oxide + water Some non-metal oxides dissolve in water and, when they do, they produce acidic solutions.
