Metals — IGCSE Sciences - Co-Ordinated (0654) questions by topic
Ranking the reactivity of four metals against dilute hydrochloric acid, selecting the physical properties that characterise a metal such as iron, and constructing the balanced symbol equation for zinc reacting with dilute nitric acid drive the 11 metals questions from 2023 and 2024, worth 9 to 12 marks.
Explain, state and suggest are the leading command words, with calculate and name covering equation-writing and identifying specific elements. Because balancing a symbol equation or naming an ore depends on precise recall rather than partial credit, work through the equation and property questions here and submit for instant marking, so an unbalanced equation or a confused property is corrected before your next attempt.
What examiners look for
- Examiners repeatedly found that candidates did not know bauxite is the ore of aluminium.
- A recurring criticism is that few candidates gave two suitable properties, though aluminium's unreactivity or low density were both accepted where offered.
- Some candidates referred to a compound where a different chemical term was required.
- Reports note that most candidates did correctly identify at least two transition elements when asked.
