Difficulty: Easy
Correct Answer: Metal
Explanation:
Introduction / Context:The pair “Steel : Alloy” maps a specific material to its class. We must classify zinc correctly to mirror this taxonomic relation.
Given Data / Assumptions:
Concept / Approach:Preserve “instance → class.” Do not switch to functional compounds or periodic groups that do not match the instance given.
Step-by-Step Solution:Steel → alloy (class).Zinc → ? → metal (class).
Verification / Alternative check:Periodic table classification: zinc is a metal; salts are compounds formed by acid–base reactions; halogens are Group 17 non-metal elements.
Why Other Options Are Wrong:(b) Non-metal – incorrect classification of zinc.(c) Salt – a compound category, not an elemental class for zinc.(d) Halogen – different periodic group; zinc is not halogen.
Common Pitfalls:Confusing common compounds containing zinc (zinc salts) with zinc’s elemental classification.
Final Answer:Metal
