Lesson on the S block elements
S Block elements
All - Be able to recall the reactions of the S block elements with water, acids and oxygen. Along with their flame colours
Most - Be able to write the symbol the equations for these reactions
Some - Be able to work out the oxidation states of the species involved in the reaction and decide of it is a redox reaction
All S block elements are reactive with water. They have low electronegativities and so form cations.
Reactivity increases down the groups
Electronegativity decreases down the groups due to greater electron shielding of the nucleus
Reaction with water
S Block elements react with water to form hydroxides and hydrogen.
All group 1 hydroxides are soluble
In group 2 Mg(OH)2 is insoluble but, solubility increases down the group
Reaction with oxygen
S block elements all react with oxygen to form oxides
Reaction with acids
S Block elements react with acids to form a salt and hydrogen
Hydrochloric acid – chlorides
Nitric acid – nitrates
Sulphuric acid – sulphates
Research the solubility and thermal stability trends of the group 2 metal compounds specifically hydroxides, carbonates and sulphates.
