Periodic Bubbles turns the periodic table of elements into a living, floating playground. All 118 chemical elements - from hydrogen to oganesson - drift as bubbles you can pop to reveal their atomic mass, electron configuration, melting point and story. Size the bubbles by atomic mass or density, colour them by element family or state of matter, hear each element introduce itself, spin interactive 3D atom models, and test your knowledge with a three-level pop quiz. Free for students, teachers and the periodically curious - on any device, even offline.
Quick answers for curious minds - great for homework.
The periodic table is a chart of all 118 known chemical elements - the ingredients that make up everything in the universe. Elements are arranged by their atomic number (how many protons they have), and elements in the same column behave in similar ways.
There are 118 confirmed elements, from hydrogen (element 1, the lightest) to oganesson (element 118). About 90 occur naturally on Earth; the rest have been made by scientists in laboratories.
By default each colour is a family of elements - like alkali metals, noble gases or halogens. Elements in a family behave similarly. You can also colour the bubbles by state (solid, liquid or gas) or by electron block using the menus at the top.
Every element has a one- or two-letter shorthand, like H for hydrogen or Fe for iron. Some symbols come from Latin names - Fe is from "ferrum", Na (sodium) from "natrium", and Au (gold) from "aurum".
Yes - Periodic Bubbles is a free periodic table game. Pop element bubbles to collect all 118, race the three-level Pop Quiz, earn badges, and come back for the Daily Bubble - a Wordle-style daily element puzzle with a new mystery element every day.
The Daily Bubble is a daily periodic table puzzle, like Wordle but for chemistry. Guess the mystery element in six tries - after each guess the clues show whether the category, group, period, phase and atomic number are correct, too high or too low. Everyone gets the same element each day, so you can share your score grid with friends.
Yes - completely free, works on phones and tablets, and even works offline once you have visited. Pop bubbles, hear each element introduce itself, spin 3D atom models and test yourself with the Pop Quiz.
