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

Samarium (Sm) is a silvery-white rare earth metal that is moderately hard and has important magnetic properties. It tarnishes slowly in air and ignites at high temperatures. Key details about Samarium (Sm) are as follows:

Uses: Used in samarium-cobalt (SmCo) permanent magnets (high temperature stability), neutron absorber in nuclear reactors, catalysts, infrared absorbing glass, and in samarium-153 for cancer treatment (radiotherapy).

Production/Extraction: Extracted from monazite and bastnäsite ores. China is the dominant producer. Moderately abundant among rare earth elements.

History: Discovered in 1879 by Paul-Émile Lecoq de Boisbaudran in France through spectroscopic analysis of the mineral samarskite. Named after the mineral, which was named after Russian mining engineer Vasili Samarsky-Bykhovets.

Health Effects & Safety: Low to moderate toxicity. Samarium compounds can be irritating. Radioactive isotope Sm-153 is used medically for pain relief in bone cancer. Dust may be flammable.

Price/Market: Moderate to high pricing. Demand driven by high-temperature magnets and medical applications. Supply tied to rare earth production.

Properties: Moderately hard, tarnishes slowly in air, exhibits +2 and +3 oxidation states, forms powerful high-temperature permanent magnets with cobalt, and has seven naturally occurring isotopes (some slightly radioactive).
