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

Beryllium (Be) is a rare, steel-gray alkaline earth metal that is lightweight, stiff, and has excellent thermal properties. It is toxic and requires careful handling but is valuable in specialized applications. Key details about Beryllium (Be) are as follows:

Uses: Used in aerospace components, X-ray windows (transparent to X-rays), nuclear weapons and reactors (as a neutron reflector and moderator), and in copper-beryllium alloys for springs, electrical contacts, and non-sparking tools.

Production/Extraction: Extracted primarily from bertrandite and beryl ores through sulfuric acid processing followed by electrolysis. The United States is the world's leading producer, with significant deposits in Utah.

History: Discovered by Louis-Nicolas Vauquelin in 1798 in beryl and emerald gemstones. Originally called "glucinium" due to the sweet taste of its salts. Isolated in metallic form by Friedrich Wöhler and Antoine Bussy independently in 1828.

Health Effects & Safety: Highly toxic—beryllium dust and fumes can cause chronic beryllium disease (berylliosis), a serious lung condition. Handling requires strict safety protocols and ventilation. Not considered a carcinogen by all agencies but treated with extreme caution.

Price/Market: Expensive due to limited supply and difficult extraction. Classified as a critical and strategic material for defense applications.

Properties: Exceptionally high melting point for a light metal (1287°C), high stiffness-to-weight ratio, excellent heat dissipation, and X-ray transparent. Forms a protective oxide layer.
