The periodic table
Question
- A. It allowed for the grouping of elements by similar properties
- B. It led to the use of atomic weight instead of atomic number
- C. It made the periodic table more complex
- D. It eliminated the need for gaps in the table
Answer
The correct option is It allowed for the grouping of elements by similar properties.
Explanation
The correct option is It allowed for the grouping of elements by similar properties. It allowed for the grouping of elements by similar properties is correct because it directly supports the approved learning objective to explain why some elements were placed in inappropriate groups when atomic weight order was followed strictly. This is tested in the subtopic Development of the periodic table within The periodic table, so the reasoning must stay within AQA GCSE Chemistry 8462 Unit 4.1. The other options are weaker because they either confuse a nearby Chemistry concept, use the wrong subtopic context, or do not answer Development of the periodic table precisely. Repair marker df40e9e6 keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Misplacement of Elements
Students often think that all elements can be placed in groups based solely on their atomic weight without considering their properties.
Emphasize that elements were sometimes placed in inappropriate groups because atomic weight did not account for their chemical properties, leading to inconsistencies in the periodic table.
