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

Zirconium (Zr) is a lustrous, grayish-white, strong, ductile transition metal that is highly resistant to corrosion. It is primarily used in nuclear applications and chemical processing. Key details about Zirconium (Zr) are as follows:

Uses: Used extensively in nuclear reactors (fuel cladding due to low neutron absorption and corrosion resistance), chemical processing equipment (resistant to acids and alkalis), high-performance pumps and valves, zirconia ceramics (knife blades, dental crowns, thermal barriers), and cubic zirconia (diamond simulant in jewelry).

Production/Extraction: Extracted from zircon sand (zirconium silicate) through the Kroll process or other reduction methods. Extremely difficult to separate from hafnium due to chemical similarity. Australia, South Africa, and China are major producers.

History: Identified as an element by Martin Heinrich Klaproth in 1789 in zircon. First isolated by Jöns Jakob Berzelius in 1824. Named from Arabic "zargun" (gold-colored), referring to zircon gemstones. Hafnium-free zirconium became critical with nuclear reactor development.

Health Effects & Safety: Generally considered non-toxic and biologically inert. Used in surgical implants due to biocompatibility. Zirconium powder is a fire hazard. Zirconium compounds are safe; zirconium oxide used in deodorants.

Price/Market: Moderate to high pricing; nuclear-grade (hafnium-free) zirconium is more expensive. Demand driven by nuclear power industry. Geopolitical factors affect supply chains.

Properties: Excellent corrosion resistance (forms protective oxide layer), high melting point (1855°C), low neutron absorption cross-section (critical for nuclear applications), strong and ductile, and chemically very similar to hafnium.
