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

Sodium (Na) is a soft, silvery-white, highly reactive alkali metal that must be stored under oil to prevent oxidation. It is the sixth most abundant element on Earth and essential for life. Key details about Sodium (Na) are as follows:

Uses: Used in sodium vapor lamps (street lighting), as a heat transfer agent in nuclear reactors, in organic synthesis as a reducing agent, in soap and detergent manufacturing, and in salt production. Sodium compounds are ubiquitous in daily life.

Production/Extraction: Produced by electrolysis of molten sodium chloride (Downs process). Salt (NaCl) is obtained from seawater evaporation or mining of halite deposits. Sodium is never found free in nature due to its reactivity.

History: First isolated by Humphry Davy in 1807 through electrolysis of caustic soda (NaOH). The name derives from "soda" (sodium carbonate), which comes from Arabic "suwwad" (saltwort plant). Sodium compounds have been used since ancient times.

Health Effects & Safety: Violently reactive with water, producing hydrogen gas and heat (fire/explosion risk). Metallic sodium is corrosive to skin. Sodium ions (Na⁺) are essential for nerve transmission, muscle contraction, and fluid balance, but excessive salt intake can cause hypertension.

Price/Market: Relatively inexpensive due to abundant raw materials. Industrial demand is stable, with specialty applications commanding higher prices.

Properties: Extremely soft (can be cut with a knife), low melting point (98°C), tarnishes immediately in air, reacts vigorously with water, floats on water, and exhibits characteristic yellow-orange flame color.
