## What is Elementa?

Elementa is a periodic table that shows its sources. Every element, every nuclide in NUBASE2020, the Standard Model's particles and the nucleons, each value with its dataset, uncertainty and unit beside it. Where no published source gives a value, Elementa shows it as missing, never as a guess.

Free to download, with no ads and no account. All the data is inside the app, so it works offline, in English and ten more languages.

THE TABLE
• All 118 elements, from the whole table on one screen to large cells: pinch to zoom, or ⌘+ and ⌘− on a Mac.
• Colour it by group or period, by one of seven properties (as bars in 3D too), or by a question: is it radioactive, could you touch, smell or see it? Turn a dial to see each element's state at any temperature, or what was known in any year.
• Colours that stay readable with colour blindness; VoiceOver reads each cell: its name, symbol, number and the property shown.

EACH ELEMENT
• Every value with its source, under five headings, in your units: atomic weight, electron configuration, ionization energies, electron affinity, electronegativities, radii, oxidation states, melting and boiling points, density, crystal structures, thermal and electrical properties, abundances, discovery, its look and smell, and the EU's hazard classes.
• Its orbital diagram and its ions', and its visible spectral lines in their colours.
• The whole atom in 3D: all its electrons, computed by density-functional theory, to scale, and a zoom down to its nucleus where that is measured. The dots keep being drawn again, as new measurements would find the electrons.
• Its own orbitals in 3D, from the same calculation (hydrogen's exact), as surfaces or as dots from |ψ|².
• Hydrogen taking in and giving out light (optical Bloch equations).
• Its crystal structures in 3D, measured, from the Crystallography Open Database, as atoms and bonds or as the electrons' density; where the source measured how far heat moves the atoms, they swing that far.

NUCLIDES
• Mass, binding energy, spin and parity, half-life, decay modes and branching ratios, natural abundance and, where measured, charge radius, from AME2020, NUBASE2020 and published measurements.
• Each nuclide's page: its Q-values, separation energies and activity, its nucleus in 3D where measured, its decay chain, and a sample decaying at random.
• The chart of nuclides by decay, half-life, binding energy, Q-value or separation energy, the magic numbers marked, and the valley of stability in 3D.

PARTICLES
• The quarks, leptons and bosons of the Standard Model, and the proton and neutron, from the Particle Data Group's 2026 Review of Particle Physics: mass, charge, spin, lifetime and decays. Watch the electron's spin turn in a magnetic field, and a nucleon's charge in 3D.

TOOLS
• 19 tools: compare elements, plot any property, molar mass, molecule shapes (VSEPR in 3D, with polarity), reactions, concentration, colligative properties, equilibrium, acids and bases, empirical formula, gas laws, reaction rates, electrochemistry, units, half-life and activity, Q-values, spectra, physical constants, and export to XLSX, CSV or JSON with every value's source.
• Ask in your own words, such as “What is gold and how heavy is it?”, answered on your device from the data alone, its elements lit on the table. Siri and Shortcuts can ask too.
• Find any element, nuclide or particle as you type; Spotlight finds the elements.
• A widget shows an element a day, with a sourced fact.

SOURCES
Settings › Sources credits every source with its licence and version, AME2020, NUBASE2020, the Review of Particle Physics, the Crystallography Open Database, NIST's atomic spectra and Wikidata among them.

LOOKS AND COINS
Earn coins each day you use it, or buy a pack, and spend them on looks: eight table colour schemes and, on iPhone and iPad, eight app icons. Only the looks cost coins; the rest is free. Your coins work in every Invader Studio app.

Elementa runs on iPhone, iPad and Mac.
