Question

A. They have one electron in their outer shell.
B. They have a full outer shell.
C. They have eight electrons in their outer shell.
D. They have no electrons in their outer shell.

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 explain that Group 1 elements have one electron in their outer shell. 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 4ecf88c0 keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.

Common mistake

Misunderstanding Outer Electrons

Students often think that Group 1 elements have more than one outer electron.

Remember that Group 1 elements, such as lithium, sodium, and potassium, each have exactly one electron in their outer shell.
