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

Californium (Cf) is a silvery, radioactive actinide metal. It is one of the most useful synthetic elements due to its strong neutron emission. Key details about Californium (Cf) are as follows:

Uses: Used as a neutron source for neutron activation analysis, in neutron radiography, to start nuclear reactors, in cancer treatment (brachytherapy), and in mining to detect gold and silver ores.

Production/Extraction: Produced by bombarding berkelium with neutrons in high-flux nuclear reactors. Only a few grams are produced worldwide each year. Extremely expensive to produce.

History: Discovered in 1950 by Stanley G. Thompson, Kenneth Street Jr., Albert Ghiorso, and Glenn T. Seaborg at UC Berkeley. Named after California.

Health Effects & Safety: Highly radioactive. Cf-252 is a strong neutron emitter. Extremely dangerous if inhaled or ingested. Requires heavy shielding and remote handling.

Price/Market: Extremely expensive (estimated at $27 million per gram for Cf-252). Available only to licensed facilities. Limited production capacity worldwide.

Properties: Radioactive, silvery metallic appearance, very dense, Cf-252 is a strong spontaneous neutron emitter, most stable isotope Cf-251 has half-life of 898 years, melting point around 900°C.
