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

Platinum (Pt) is a dense, malleable, ductile, silvery-white transition metal that is highly unreactive. It is one of the rarest elements in Earth's crust and a prominent precious metal. Key details about Platinum (Pt) are as follows:

Uses: Used in catalytic converters (automotive emissions control), jewelry, laboratory equipment, electrical contacts, dentistry, and as an investment commodity. Platinum-based drugs (e.g., cisplatin) are used in chemotherapy.

Production/Extraction: Extracted from sperrylite and cooperite ores, and as a byproduct of nickel and copper refining. South Africa accounts for the majority of global production, followed by Russia and Zimbabwe.

History: Used by pre-Columbian South Americans. First referenced in European writing by Julius Caesar Scaliger in 1557. "Discovered" by Antonio de Ulloa in 1735. Named from Spanish "platina" (little silver).

Health Effects & Safety: Metallic platinum is biologically inert and non-toxic. Platinum salts can cause allergic reactions and DNA damage (hence their use in chemotherapy). Occupational exposure to salts can cause platinosis (respiratory sensitization).

Price/Market: High-value precious metal. Price influenced by automotive demand (diesel engines primarily use platinum catalysts), jewelry market, and investment flows. Historically often more expensive than gold, though this fluctuates.

Properties: Dense, malleable, ductile, highly corrosion-resistant (noble metal), high melting point (1768°C), excellent catalytic properties, and does not oxidize in air at any temperature.
