About Eduqas A Level Chemistry 1.6 The Periodic Table
This topic covers patterns in the periodic table. Expect questions on trends and reactions of groups 2 and 7.
What you need to know
- Trends Atomic radius, ionisation energy and electronegativity across periods and down groups.
- Redox Oxidation as loss of electrons and reduction as gain, using oxidation states.
- Group 2 Reactions with water and oxygen, solubility of hydroxides and sulfates, thermal stability of carbonates.
- Group 7 Halogens as oxidising agents, displacement reactions and tests for halide ions with silver nitrate.
Common mistakes in 1.6 The Periodic Table
- Saying reactivity of halogens increases down the group.
- Mixing up the colours of silver halide precipitates.
- Confusing trends in solubility of group 2 hydroxides and sulfates.
Try three 1.6 The Periodic Table exam-style questions
1. State the colour of the precipitate when silver nitrate is added to bromide ions. (1 mark)
Show the mark scheme answer
Cream.
2. Explain why reactivity increases down group 2. (2 marks)
Show the mark scheme answer
Atomic radius increases and shielding increases (1), so outer electrons are lost more easily (1).
3. Write an equation for chlorine displacing iodide ions. (1 mark)
Show the mark scheme answer
Cl₂ + 2I⁻ → 2Cl⁻ + I₂.
