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

Barium (Ba) is a soft, silvery-white alkaline earth metal that is highly reactive and never found free in nature. It oxidizes rapidly in air and reacts vigorously with water. Key details about Barium (Ba) are as follows:

Uses: Used in drilling fluids for oil and gas wells (barium sulfate increases density), medical imaging (barium sulfate contrast media for X-rays and CT scans of digestive system), glass manufacturing, ceramics, rat poison (barium carbonate), fireworks (green color), and in some specialized alloys.

Production/Extraction: Extracted from barite (barium sulfate) and witherite (barium carbonate) ores through thermal reduction. China, India, and Morocco are major barite producers. Metallic barium has limited direct use; compounds are more important.

History: Distinguished as a new element by Carl Wilhelm Scheele in 1774, though not isolated until 1808 by Humphry Davy through electrolysis. Named from Greek "barys" (heavy) due to the high density of barite mineral.

Health Effects & Safety: Soluble barium compounds are highly toxic, affecting the heart and nervous system. Barium sulfate is insoluble and safe for medical use (not absorbed by body). Metallic barium reacts with water and must be stored under oil. Chronic occupational exposure can cause baritosis (benign lung condition).

Price/Market: Barite (barium sulfate) is relatively inexpensive and widely used in drilling fluids. Medical-grade barium sulfate commands higher prices. Oil industry drives major demand.

Properties: Soft and reactive, burns with characteristic yellow-green flame color, reacts vigorously with water, exhibits +2 oxidation state exclusively, high density, and forms insoluble sulfate (barite, important ore and medical compound).
