CLUSTER ELEMENTS-PERIODIC-TABLE · 23 ENTRIES · EARLIEST ENTRY 2025-07-28
Interactive periodic table apps
This cluster consists of interactive periodic table and chemistry reference applications, primarily for educational purposes, covering element properties, quizzes, and molecular calculations. The dated entries are sparse, with only five records from July 2025 to July 2026, making the timeline shape too thin to read a trend from—it predates the index or members are undated. Traction leaders based on activity signal are ChemSearch, valence-chemistry-quiz, and pairinteraction, each with zero stars.
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 20 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
