Which option ranks first in d-block metals in groups 11 and 12 when ascending periodic-table group number is ranked and ascending periodic-table period number resolves ties?

Answer options

• Option: zinc (group 12, period 4)
  "zinc (group 12, period 4)" vs. "copper (group 11, period 4)" Zinc satisfies the filter and shares; misses the target mapping. zinc (group 12, period 4) remains in ranking scope d-block metals in groups 11 and 12. The task targets this mapping, so zinc (group 12, period 4) remains wrong in this prompt.
• Option: gold (group 11, period 6)
  "gold (group 11, period 6)" vs. "copper (group 11, period 4)" Gold satisfies the filter and group; misses the target mapping. gold (group 11, period 6) remains in ranking scope d-block metals in groups 11 and 12. The task targets this mapping, so gold (group 11, period 6) remains wrong in this prompt.
• Option: silver (group 11, period 5)
  "silver (group 11, period 5)" vs. "copper (group 11, period 4)" Silver satisfies the filter and group; misses the target mapping. silver (group 11, period 5) remains in ranking scope d-block metals in groups 11 and 12. The task targets this mapping, so silver (group 11, period 5) remains wrong in this prompt.
• Correct: copper (group 11, period 4)
  "copper (group 11, period 4)" - target Copper satisfies the filter, shares the lowest group number 11,. copper (group 11, period 4) remains in ranking scope d-block metals in groups 11 and 12. The task targets this mapping, and copper (group 11, period 4) remains correct in this prompt.

Solution

copper (group 11, period 4)

copper (group 11, period 4) is correct: filter: d-block and group 11 or 12 limits the pool; ascending periodic-table group number creates a tie resolved by ascending periodic-table period number with group number, then period number, then entity id. The prompt targets copper (group 11, period 4), so the graph keeps this mapping stable against close alternatives. Source: Wikidata. As of: 2026-02-13.

Fun fact

Ranking with tiebreaker requires a filter, rank metric, tiebreaker, and deterministic sort key. copper (group 11, period 4) carries the additional dataset detail d-block metals in groups 11 and 12. The graph therefore uses a multi-hop graph path;
