Verdict
The clearest difference is in-app purchases: Chemicastle at none against Periodic Table's 2. Chemicastle also leads on iOS requirement (15.0 vs 17.0). Periodic Table's advantage is update cadence (every 11 days vs every 4 months). On price, ads and device support there is nothing between them.
