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

Mendelevium (Md) is a radioactive actinide metal. It was the first element to be synthesized one atom at a time. Key details about Mendelevium (Md) are as follows:

Uses: No practical applications. Used only in scientific research to study the properties of heavy elements.

Production/Extraction: Produced by bombarding einsteinium with alpha particles in particle accelerators. Only produced in atom-by-atom quantities.

History: Discovered in 1955 by Albert Ghiorso, Glenn T. Seaborg, Bernard Harvey, Gregory Choppin, and Stanley Thompson at UC Berkeley. Named after Dmitri Mendeleev, creator of the periodic table.

Health Effects & Safety: Highly radioactive. Extreme rarity means limited toxicity data, but assumed to be highly dangerous.

Price/Market: Not commercially available. Produced only for research.

Properties: Radioactive, most stable isotope Md-258 has half-life of 51.5 days, melting point around 827°C (estimated).
