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

Tantalum (Ta) is a hard, blue-gray, lustrous transition metal that is highly corrosion-resistant and has one of the highest melting points of all elements. It is ductile and can be drawn into fine wire. Key details about Tantalum (Ta) are as follows:

Uses: Primarily used in capacitors for electronics (smartphones, computers, automotive electronics), superalloys for jet engines and rockets, chemical processing equipment (corrosion resistance), surgical implants and bone repair (biocompatible), sputtering targets for semiconductors, and as a filament material in some light bulbs.

Production/Extraction: Extracted from tantalite ore, often found alongside niobium deposits. Major producers include Brazil, Australia, and Rwanda. Extraction is complex due to the need to separate it from chemically similar niobium.

History: Discovered in 1802 by Anders Ekeberg in Sweden. It was named after Tantalus from Greek mythology, who was punished by having to stand in water that receded when he tried to drink—symbolizing the metal's resistance to acids.

Health Effects & Safety: Tantalum metal is considered biologically inert and is biocompatible, making it safe for medical implants. However, tantalum dust can be irritating to the respiratory tract and eyes.

Price/Market: A high-value metal due to its critical role in electronics and aerospace. Prices can fluctuate based on supply chain stability and demand from the tech industry.

Properties: It has an extremely high melting point (3017°C), second only to tungsten among metals. It is highly ductile and can be worked into very thin foils. It forms a stable, insulating oxide layer that makes it resistant to corrosion.
