The periodic table
Question
- A. It can support or refute scientific ideas.
- B. It is unnecessary for scientific progress.
- C. It only serves to confirm existing theories.
- D. It complicates the understanding of elements.
Answer
The correct option is It can support or refute scientific ideas..
Explanation
The correct option is It can support or refute scientific ideas.. It can support or refute scientific ideas. is correct because it directly supports the approved learning objective to explain how discovery of predicted elements supported Mendeleev's table. 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 2dbd8b08 keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Misunderstanding Mendeleev's Predictions
Students often think that Mendeleev's predictions were purely random rather than based on chemical properties.
Emphasize that Mendeleev used observed chemical properties to predict the existence and properties of undiscovered elements, which later supported his periodic table.
