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

Helium (He) is a colorless, odorless, tasteless noble gas and the second most abundant element in the universe, though rare on Earth. It is chemically inert and has the lowest boiling point of all elements. Key details about Helium (He) are as follows:

Uses: Used in cryogenics (cooling superconducting magnets in MRI machines and particle accelerators), as a protective atmosphere in welding, in airships and balloons, and in diving gas mixtures.

Production/Extraction: Extracted from natural gas deposits (where it accumulates from radioactive decay of uranium and thorium) through fractional distillation. Major sources include the United States, Qatar, and Algeria.

History: First detected in the solar spectrum during an 1868 eclipse by Pierre Janssen and Joseph Norman Lockyer, who named it after Helios, the Greek sun god. First isolated on Earth by William Ramsay in 1895.

Health Effects & Safety: Non-toxic and inert, but can cause asphyxiation by displacing oxygen. Inhaling helium changes voice pitch temporarily but can be dangerous if oxygen is excluded.

Price/Market: Considered a non-renewable resource with concerns about future shortages. Price has fluctuated significantly due to supply constraints and strategic reserves being depleted.

Properties: Second lightest element, remains liquid down to absolute zero at normal pressure, extremely low reactivity (no stable compounds), and high thermal conductivity.
