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

Vanadium (V) is a hard, silvery-gray transition metal that is ductile and resistant to corrosion. It is relatively abundant in Earth's crust and is primarily used in alloys and chemical applications. Key details about Vanadium (V) are as follows:

Uses: Primarily used in steel alloys (ferrovanadium) to increase strength, toughness, and wear resistance for tools, springs, and high-speed machinery. Also used in vanadium redox flow batteries (energy storage), as a catalyst in chemical processes, and in titanium alloys for aerospace.

Production/Extraction: Extracted from magnetite, vanadinite, and carnotite ores, or recovered from slag in iron and steel production. China, Russia, and South Africa are major producers. Also present in petroleum and coal, recovered during processing.

History: Discovered by Andrés Manuel del Río in 1801 in Mexico but dismissed due to confusion with chromium. Rediscovered by Nils Gabriel Sefström in 1830 in Sweden. Named after Vanadis, the Scandinavian goddess of beauty, due to its colorful compounds.

Health Effects & Safety: Vanadium compounds can be toxic if inhaled or ingested in large amounts. Essential in trace amounts for some organisms (ascidians). Occupational exposure should be monitored. Some vanadium compounds show promise in diabetes treatment research.

Price/Market: Price driven by steel industry demand, particularly from China. Emerging interest in vanadium batteries for grid-scale energy storage could significantly impact future markets.

Properties: Excellent corrosion resistance due to oxide layer, exhibits multiple oxidation states (+2 to +5) with different colors, ductile and malleable, good structural strength, and compounds are often brightly colored (yellow, green, blue).
