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

Lithium (Li) is the lightest metal and solid element, appearing as a soft, silvery-white alkali metal that is highly reactive with water and air. It is crucial for modern battery technology and has important pharmaceutical applications. Key details about Lithium (Li) are as follows:

Uses: Primarily used in rechargeable lithium-ion batteries for electric vehicles, smartphones, and laptops. Also used in ceramics, glass production, lubricating greases, and as a mood-stabilizing medication (lithium carbonate).

Production/Extraction: Extracted from brine deposits (evaporation ponds in salt flats) and hard rock mining (spodumene ore). Major producers include Australia, Chile, Argentina, and China. The "Lithium Triangle" in South America holds vast brine reserves.

History: Discovered by Johan August Arfwedson in 1817 in a petalite mineral from Sweden. First isolated by William Thomas Brande and Sir Humphry Davy in 1821 through electrolysis.

Health Effects & Safety: Highly reactive and corrosive; must be stored in mineral oil. Lithium compounds can be toxic in high doses but therapeutic at controlled levels for bipolar disorder. Fires are difficult to extinguish.

Price/Market: Prices have surged dramatically due to electric vehicle demand, making it a critical mineral for the energy transition. Supply concerns and geopolitical factors significantly impact markets.

Properties: Lowest density of all metals (floats on water), highest specific heat of any solid element, soft enough to cut with a knife, and tarnishes rapidly in air.
