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

Tellurium (Te) is a brittle, silvery-white metalloid that is extremely rare in Earth's crust (rarer than platinum). It is mildly toxic and imparts a garlic odor to the breath when ingested. Key details about Tellurium (Te) are as follows:

Uses: Used in metallurgy (improving machinability of copper and steel alloys, especially free-machining steel), thermoelectric devices (bismuth telluride), solar panels (cadmium telluride CdTe thin films), phase-change memory devices, rubber vulcanization, and in ceramics (color additive).

Production/Extraction: Produced as a byproduct of copper refining from anode slimes (tellurium is enriched during electrolytic refining). Canada, Japan, and the United States are major producers. One of the rarest stable elements.

History: Discovered by Franz-Joseph Müller von Reichenstein in 1782 in gold ores from Transylvania. Named by Martin Heinrich Klaproth in 1798 from Latin "tellus" (earth), complementing selenium (named after the moon).

Health Effects & Safety: Moderately toxic. Exposure causes garlic breath odor (dimethyl telluride), fatigue, and nausea. Can cause developmental effects. Organotellurium compounds can be highly toxic. No known biological role. Occupational exposure should be controlled.

Price/Market: Expensive due to extreme rarity and limited supply. Growing demand from solar cells (CdTe) and thermoelectrics. Supply constraints limit applications. Classified as a critical mineral.

Properties: Brittle at room temperature, semiconductor properties, exhibits metallic luster, shows -2, +4, and +6 oxidation states, forms garlic-smelling compounds, photoconductive (conductivity increases with light), and intermediate properties between metals and nonmetals.
