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

Polonium (Po) is a radioactive, silvery-gray semi-metal or metal. It is extremely rare and highly volatile. Key details about Polonium (Po) are as follows:

Uses: Used in static eliminators (brushes for film/dust), as a neutron source (when mixed with beryllium), and as a heat source in radioisotope thermoelectric generators (RTGs) for satellites (historically).

Production/Extraction: Found in trace amounts in uranium ores (pitchblende). Produced artificially by bombarding bismuth with neutrons in nuclear reactors. Russia is the primary producer.

History: Discovered in 1898 by Marie and Pierre Curie in residues of pitchblende. Named after Poland, Marie Curie's homeland, to publicize its lack of independence.

Health Effects & Safety: Extremely radiotoxic. Polonium-210 emits alpha particles that are harmless outside the body but deadly if ingested or inhaled (billions of times more toxic than cyanide by mass). Use is strictly controlled.

Price/Market: Not commercially traded openly due to half-life (138 days for Po-210) and extreme toxicity/security risks. Sold only to licensed facilities for industrial/scientific use.

Properties: Radioactive, volatile (sublimes at relatively low temperatures), silvery metallic appearance, chemically resembles tellurium and bismuth, and dissolves in dilute acids.
