Which item belongs in the same documented group as neon in the chemical element family scope?

Answer options

• Option: iron
  "iron" vs. "krypton" Iron has a documented but different; misses the target mapping. iron stays thematically plausible but misses the requested target. The task targets this mapping, so iron remains wrong in this prompt. iron stays relevant in the graph profile but does not carry the requested relation.
• Option: sodium
  "sodium" vs. "krypton" Sodium is stored as an alkali metal; misses the target mapping. sodium stays thematically plausible but misses the requested target. The task targets this mapping, so sodium remains wrong in this prompt. sodium stays relevant in the graph profile but does not carry the requested relation.
• Correct: krypton
  "krypton" - target Krypton is another source-backed candidate in the noble-gas. krypton matches the requested target of this prompt most precisely. The task targets this mapping, and krypton remains correct in this prompt. krypton remains tied to the requested relation through direct in the graph profile.
• Option: oxygen
  "oxygen" vs. "krypton" Oxygen remains in the same scope but in; misses the target mapping. oxygen stays thematically plausible but misses the requested target. The task targets this mapping, so oxygen remains wrong in this prompt. oxygen stays relevant in the graph profile but does not carry the requested relation.

Solution

krypton

"krypton" is correct: Krypton is another source-backed candidate in the noble-gas group. The prompt targets krypton, so the graph keeps this mapping stable against close alternatives. Source: Wikidata. As of: 2026-02-13.

Fun fact

same_group_pick uses two direct membership claims here and keeps all distractors in other groups of the same scope. krypton stays anchored with additional dataset context. The graph therefore uses a direct graph path.
