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

Argon (Ar) is a colorless, odorless, tasteless noble gas that is the third most abundant gas in Earth's atmosphere (0.93%). It is chemically inert under normal conditions and is the most abundant noble gas on Earth. Key details about Argon (Argon) are as follows:

Uses: Used as an inert shielding gas in welding (especially TIG and MIG), in incandescent and fluorescent lighting, in semiconductor manufacturing, as a protective atmosphere in metal production, in wine preservation, and in diving (for dry suit inflation).

Production/Extraction: Obtained as a byproduct of liquid air fractional distillation during oxygen and nitrogen production. Argon is more economically extracted than other rare noble gases due to its atmospheric abundance.

History: Discovered in 1894 by Lord Rayleigh and William Ramsay through experiments investigating the density of nitrogen. Named from Greek "argos" meaning "inactive" or "lazy" due to its lack of reactivity.

Health Effects & Safety: Non-toxic and chemically inert. Can cause asphyxiation by displacing oxygen in confined spaces. Heavier than air, so it accumulates in low areas. Liquid argon can cause frostbite. No biological role.

Price/Market: Less expensive than other noble gases (except helium) due to atmospheric abundance. Steady demand from welding and metallurgical industries. Price sensitive to industrial production levels.

Properties: Completely inert under normal conditions (no stable compounds), colorless and odorless, emits purple-blue light when electrically excited, about 1.4 times denser than air, and third most abundant atmospheric gas after nitrogen and oxygen.
