Verdict
The clearest difference is price: Periodic Table at Free against 3D Elements's $1.99. Periodic Table also leads on update cadence (every 5 days vs every 4 months). 3D Elements's advantage is in-app purchases (none vs 3). On ads, device support and iOS requirement there is nothing between them.
