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

Curium (Cm) is a hard, dense, silvery radioactive actinide metal that glows purple in the dark due to its intense radioactivity. Key details about Curium (Cm) are as follows:

Uses: Used in alpha particle X-ray spectrometers for analyzing rock composition (Mars rovers). Cm-244 is used as a power source in radioisotope thermoelectric generators for remote locations and space applications.

Production/Extraction: Produced by bombarding plutonium or americium with neutrons in nuclear reactors. Extremely difficult and expensive to produce in significant quantities.

History: Discovered in 1944 by Glenn T. Seaborg, Ralph A. James, and Albert Ghiorso at UC Berkeley. Named after Marie and Pierre Curie in recognition of their pioneering work on radioactivity.

Health Effects & Safety: Highly radioactive and dangerous. Strong alpha emitter. Extremely hazardous if inhaled or ingested. Requires remote handling and heavy shielding.

Price/Market: Not commercially available. Produced only for specific scientific and space applications at great expense.

Properties: Radioactive, silvery metallic appearance, glows purple in the dark, very dense, most stable isotope Cm-247 has half-life of 15.6 million years (but Cm-244 is more commonly used), melting point around 1345°C.
