3QuestionMetals Non-Metals and MetalloidsAssessment Practice
4 marks~6 minCriterion A
A student tests two materials using the circuit shown. Material A is shiny and metallic; when placed in the gap, the bulb lights up. Material B is dull and non-metallic; when placed in the gap, the bulb does not light up.
a
Identify the electrical property of metals demonstrated by Material A. [1]
b
Explain why Material A causes the bulb to light up but Material B does not. [2]
c
A third material, silicon, is tested in the same circuit. The bulb glows very dimly. Suggest what this tells you about silicon's classification and its ability to conduct electricity. [1]

4QuestionGroups and Periods ExplainedAssessment Practice
12 marks~18 minCriterion D
A fireworks manufacturer uses alkali metal compounds to create colours in displays. Scientists are concerned about the environmental effects of these compounds after a display.
a
Identify two alkali metals used in fireworks and state the colour each one produces. [2]
b
Explain two environmental impacts that occur when these metal compounds are released during a fireworks display. [4]
c
A city council is deciding whether to replace traditional fireworks with an alternative that uses compounds containing no alkali metals. The alternative produces less air pollution but results in noticeably duller colours. Analyse whether the council should make this switch, using evidence from both the environmental and display-quality perspectives. [6]
