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

Potassium (K) is a soft, silvery-white alkali metal that is highly reactive and must be stored under oil. It is the seventh most abundant element in Earth's crust and is essential for all living organisms. Key details about Potassium (K) are as follows:

Uses: Potassium compounds are used extensively in fertilizers (essential plant nutrient), in soap and glass production, as potassium chloride (salt substitute), in fireworks (purple flame), gunpowder, and in chemical synthesis. Metallic potassium is used in some organic reactions.

Production/Extraction: Produced by electrolysis of molten potassium chloride or by thermal reduction of potassium chloride with sodium. Potassium compounds are mined as potash (primarily potassium chloride) from ancient evaporite deposits or extracted from brines.

History: First isolated by Humphry Davy in 1807 through electrolysis of caustic potash (potassium hydroxide). Named from English "potash" (pot ashes), which refers to plant ashes soaked in water in pots. The symbol K comes from Latin "kalium."

Health Effects & Safety: Metallic potassium reacts violently with water, producing hydrogen gas and heat (explosion risk). Potassium ions (K⁺) are essential for nerve function, muscle contraction, heart rhythm, and cellular processes. Dietary deficiency causes weakness and cardiac problems; excess causes hyperkalemia.

Price/Market: Potash (potassium fertilizer) prices fluctuate based on agricultural demand and global supply. Canada, Russia, and Belarus are major producers. Geopolitically important for food security.

Properties: Even more reactive than sodium, soft enough to cut with a knife, low density (floats on water), reacts violently with water, burns with violet/lilac flame color, melts at 63°C, and tarnishes rapidly in air.
