Isotope Explorer
Explore stable and radioactive isotopes, decay chains, relative abundances, and half-life calculations — built for classrooms and curious learners.
Everything you need to explore isotopes
Interactive periodic table
Pick any element and see which isotopes are in our curated dataset, with quick search by name, symbol, or atomic number.
Decay chains & modes
Follow daughter nuclides through authored decay paths with notation, half-lives, and decay mode symbols.
Half-life calculator
Compute remaining quantity or time to a target fraction using N = N₀ × (½)^(t / t½). Educational only.
Relative abundance
Compare natural mole-percent abundances for stable isotopes side by side with clear bar charts.
