What is the Interactive Periodic Table?

The Interactive Periodic Table is a free, modern web application that displays all 118 elements with detailed properties, 3D Bohr model visualizations, crystal structure renderings, and text-to-speech pronunciation. It works on desktop, tablet, and mobile devices.

What information is available for each element?

Each element page includes atomic number, atomic mass, electron configuration, physical properties (density, melting and boiling points, state of matter), chemical properties (electronegativity, ionization energy, electron affinity), an interactive 3D Bohr model, 3D crystal structure, and an AI-generated educational summary.

Can I use this periodic table for teaching?

Yes. The Interactive Periodic Table includes a full-screen mode designed for projectors and classroom presentations. All content is educational and completely free to use without registration.

Does it work on mobile devices?

Yes. The web app is fully responsive and also available as native iOS and Android apps that can be downloaded from the app stores.

What are the 3D visualizations?

Each element features an interactive 3D Bohr model showing electron shells orbiting the nucleus, and a 3D crystal structure rendering showing the element's atomic arrangement. Both are powered by Three.js and React Three Fiber.

Is this periodic table free?

Yes, the Interactive Periodic Table is completely free with no registration, no ads, and no data collection required.

How many elements are included?

All 118 confirmed elements from Hydrogen (H, atomic number 1) through Oganesson (Og, atomic number 118) are included with full data and visualizations.

Can I hear how element names are pronounced?

Yes. The text-to-speech feature allows you to hear the correct pronunciation of any element name. This works on both the web version and native mobile apps.

Brief Introduction

Yttrium (Y) is a silvery-metallic transition metal that is relatively stable in air due to an oxide film. Despite its name and association with rare earths, it is actually more abundant than lead. Key details about Yttrium (Y) are as follows:

Uses: Used in yttrium aluminum garnet (YAG) lasers, phosphors for LED and CRT displays (red phosphor in televisions), yttria-stabilized zirconia (thermal barrier coatings, oxygen sensors, fuel cells), superconductors (YBCO), and in certain metal alloys to improve strength and oxidation resistance.

Production/Extraction: Extracted from bastnäsite and monazite ores through ion exchange or solvent extraction processes, similar to rare earth elements. China dominates production. Often co-occurs with lanthanides, though yttrium is chemically distinct (Group 3).

History: Discovered in 1794 by Johan Gadolin in a mineral from Ytterby, Sweden (which also gave names to erbium, terbium, and ytterbium). Isolated in relatively pure form by Friedrich Wöhler in 1828. Named after Ytterby.

Health Effects & Safety: Compounds have low to moderate toxicity. No known biological role. Occupational exposure should be controlled. Yttrium can accumulate in liver and bones. Generally safer than heavy rare earths.

Price/Market: Moderate to high pricing depending on purity. Demand driven by electronics, phosphors, and advanced ceramics. Supply tied to rare earth mining and geopolitics, particularly China's export policies.

Properties: Relatively stable in air (forms protective oxide), similar chemical behavior to lanthanides (often classified with rare earths), exhibits +3 oxidation state almost exclusively, moderate density, and useful in forming stable oxides for high-temperature applications.
