Question
- A. They have one electron in their outer shell
- B. They are noble gases
- C. They are non-metals
- D. They have high melting points
Answer
The correct option is They have one electron in their outer shell.
Explanation
The correct option is They have one electron in their outer shell. They have one electron in their outer shell is correct because it directly supports the approved learning objective to identify Group 1 elements as alkali metals. This is tested in the subtopic Group 1 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 Group 1 precisely. Repair marker 76c11920 keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Misidentifying Group 1 Elements
Students often confuse Group 1 elements with transition metals, thinking they are the same due to both being metals.
Remember that Group 1 elements are specifically alkali metals, which have one electron in their outer shell, while transition metals are found in the center of the periodic table and have different properties.
