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

Rhodium (Rh) is a rare, silvery-white, hard, and highly reflective transition metal belonging to the platinum group. It is the most expensive precious metal and has exceptional catalytic properties. Key details about Rhodium (Rh) are as follows:

Uses: Primarily used in catalytic converters for automobiles (reduces nitrogen oxide emissions), in jewelry (rhodium plating for white gold and silver provides tarnish resistance and luster), in searchlights and mirrors (highly reflective coating), and as a catalyst in chemical synthesis.

Production/Extraction: Produced as a byproduct of platinum and nickel mining. South Africa produces about 80% of global supply, with Russia as a secondary source. Extremely rare—world production is only a few tens of tons annually.

History: Discovered by William Hyde Wollaston in 1803 in platinum ore from South America. Named from Greek "rhodon" (rose) due to the rose-red color of one of its chloride compounds.

Health Effects & Safety: Generally considered non-toxic and biologically inert. Some rhodium compounds can cause staining and allergic reactions. No known biological role. Safe for jewelry applications.

Price/Market: Extremely expensive and volatile pricing (often $10,000-$20,000+ per troy ounce, sometimes exceeding gold and platinum). Price driven by automotive catalytic converter demand and supply constraints. Supply concentration in South Africa creates geopolitical risks.

Properties: Highest reflectivity of any metal, excellent catalytic properties (especially for NOx reduction), extremely resistant to corrosion and oxidation, high melting point (1964°C), hard and durable, and exhibits primarily +3 oxidation state.
