The periodic table
Question
- A. It shows the number of outer-shell electrons.
- B. It determines the element's atomic mass.
- C. It indicates the number of protons in the nucleus.
- D. It defines the element's state of matter.
Answer
The correct option is It shows the number of outer-shell electrons..
Explanation
The correct option is It shows the number of outer-shell electrons.. It shows the number of outer-shell electrons. is correct because it directly supports the approved learning objective to explain that columns in the periodic table are called groups. This is tested in the subtopic 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 The periodic table precisely. Repair marker 545c8130 keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Misunderstanding Groups
Students often confuse groups with periods, thinking that both refer to the same arrangement in the periodic table.
Remember that groups are the vertical columns in the periodic table, while periods are the horizontal rows. Focus on the vertical arrangement when discussing groups.
