The periodic table is one of the most powerful organizing tools in science, but to most children it looks like an impenetrable wall of abbreviations and numbers. Interactive apps transform the periodic table from a reference chart into an exploration tool. Children can tap elements to see what they look like, learn where they are found in everyday life, discover how they combine to form molecules, and understand why the table is arranged the way it is. The best apps make chemistry tangible by connecting abstract element properties to concrete objects children already know.
How We Evaluated
Each app was tested by children aged seven through fourteen over a four-week period. We assessed element identification, property understanding, and table navigation before and after use. We scored on five criteria:
- Scientific accuracy — Are element properties, atomic numbers, electron configurations, and states of matter correct and current?
- Accessibility — Does the app make chemistry concepts approachable for children without prior chemistry knowledge?
- Depth — Does the app go beyond basic identification to teach periodicity, bonding, and real-world applications?
- Engagement — Do children explore elements voluntarily and return to learn more?
- Value — Is the educational content proportional to the cost?

Detailed Reviews
NOVA Elements — Best Overall
NOVA Elements, produced by PBS, combines a complete interactive periodic table with a molecule-building game and video content from the NOVA television series. Tapping any element reveals its photo (what it looks like in pure form), essential properties (atomic number, mass, state at room temperature, melting and boiling points), discovery history, and everyday uses. The molecule builder lets children combine elements to form common compounds — two hydrogen atoms and one oxygen atom form water, with an animation showing the bonding process.
The NOVA video segments explain chemical concepts with the production quality the series is known for. Topics include why noble gases do not react, how metals conduct electricity, and why the table is arranged in periods and groups.
Why parents love it: The combination of interactive reference, molecule building, and professional video content covers chemistry from multiple angles. Children who use NOVA Elements consistently develop genuine understanding of element properties and periodic trends, not just memorization.
Limitation: iOS only. The app has not been updated recently, though the scientific content remains accurate and the interface is functional.
Periodic Table by Royal Society of Chemistry — Best Reference Tool
The Royal Society of Chemistry’s periodic table app is the most comprehensive element reference available for free. Each element page includes detailed information: atomic structure, isotopes, electron configuration, oxidation states, physical properties, discovery history, biological role, and abundance in Earth’s crust and the human body. A podcast episode accompanies each element, providing narrative context and anecdotes.
Visual tools include color-coding by element type (metals, metalloids, nonmetals), state at various temperatures, and discovery date timelines. A comparison mode lets children view two elements side by side to understand periodic trends.
Why parents love it: The depth of information rivals college-level references but is presented in accessible language. Children can start with basic properties and discover deeper layers as their knowledge grows. The podcast episodes make elements memorable through storytelling.
Limitation: The information density can overwhelm younger children. Best suited for ages ten and up, or younger children with parental guidance to navigate the content.
Toca Lab: Elements — Best for Young Children
Toca Lab: Elements introduces the periodic table to young children through play rather than instruction. Children start with a single element represented as a cute character with personality traits reflecting its real properties. Through experimentation — heating, cooling, mixing, shaking, spinning in a centrifuge — children discover new elements. Each discovered element joins the periodic table, gradually filling it through exploration.
The element characters have exaggerated personalities: sodium is excitable (it reacts violently with water), gold is shiny and proud, helium floats upward. While simplified, these characterizations are grounded in real chemistry.
Why parents love it: Five-year-olds who cannot read a traditional periodic table develop familiarity with element names, positions, and basic properties through play. When they encounter the periodic table in school years later, they have an existing framework to build on.
Limitation: The character-based approach sacrifices accuracy for accessibility. Children should understand that real elements do not have personalities, and the “experiments” are metaphorical rather than chemically accurate.
Atom and Molecule Builder — Best Molecule Building
Atom and Molecule Builder lets children construct atoms by adding protons, neutrons, and electrons, then combine atoms into molecules. Building a carbon atom requires six protons, six neutrons, and six electrons arranged in the correct shell configuration. Combining atoms into molecules follows valence rules: carbon bonds with four other atoms, oxygen with two, hydrogen with one.
The app includes challenges to build specific molecules (water, carbon dioxide, methane, glucose) and a free-build mode for experimentation. Incorrect bonds are flagged with explanations of why they do not work.
Why parents love it: Building atoms from subatomic particles teaches atomic structure at a fundamental level. The valence-based bonding system introduces chemistry concepts that prepare children for formal coursework.
Limitation: The atomic construction can be tedious for simple elements. Building hydrogen (one proton, one electron) is trivial, while building iron (twenty-six protons, thirty neutrons, twenty-six electrons) requires patience.
Element Quiz — Best Memorization Tool
Element Quiz provides flashcard-style review of element names, symbols, atomic numbers, and properties. Multiple quiz modes include symbol-to-name matching, atomic number identification, element type sorting, and property-based questions (which element has the highest melting point?). Spaced repetition ensures frequently missed elements appear more often.
Why parents love it: When children need to memorize the periodic table for school, this focused tool provides efficient practice. The spaced repetition algorithm optimizes review timing based on each child’s demonstrated knowledge.
Limitation: Pure memorization without conceptual context. Children who memorize element symbols without understanding why the table is organized as it is develop shallow knowledge. Best used alongside conceptual apps.
What to Look For
Effective periodic table apps balance accessibility with accuracy. Young children benefit from character-based or game-based approaches that build familiarity with element names and basic properties. Older children need accurate data, periodic trend explanations, and molecule-building tools. The best learning sequence starts with exploration (Toca Lab), progresses to interactive reference (NOVA Elements), and then adds molecular building and formal study tools.
Look for apps that connect elements to everyday life. Children who learn that calcium is in their bones, iron is in their blood, silicon is in their phone, and helium is in balloons develop practical context that makes abstract chemistry meaningful.
