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

Plutonium (Pu) is a silvery-gray, radioactive actinide metal that tarnishes to a dull gray when oxidized. It is one of the most important transuranium elements. Key details about Plutonium (Pu) are as follows:

Uses: Primarily used in nuclear weapons and as fuel in nuclear reactors (mixed oxide fuel). Pu-238 is used in radioisotope thermoelectric generators for spacecraft and cardiac pacemakers (historically).

Production/Extraction: Produced in nuclear reactors when uranium-238 captures neutrons and undergoes beta decay. Extracted from spent nuclear fuel through chemical reprocessing. Trace amounts occur naturally.

History: Discovered in 1940 by Glenn T. Seaborg, Edwin McMillan, Joseph W. Kennedy, and Arthur Wahl at UC Berkeley. Named after the dwarf planet Pluto.

Health Effects & Safety: Extremely radiotoxic and one of the most dangerous substances known. Alpha emitter that is especially hazardous if inhaled or ingested. Accumulates in bones and liver. Subject to strict security controls.

Price/Market: Not commercially traded. Production and possession strictly controlled by international treaties and national security regulations.

Properties: Radioactive, silvery metallic appearance that oxidizes, very dense (19.8 g/cm³), exists in six allotropic forms, pyrophoric (spontaneously ignites in air when finely divided), melting point around 640°C.
