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

Mercury (Hg) is a heavy, silvery d-block element and is the only metallic element that is liquid at standard conditions for temperature and pressure. Key details about Mercury (Hg) are as follows:

Uses: Used in thermometers, barometers, fluorescent lamps, mercury-vapor lamps, dental amalgams (declining), and historically in batteries and chlor-alkali production. Use is strictly regulated due to toxicity.

Production/Extraction: Extracted from cinnabar (mercuric sulfide) ore by roasting. China and Kyrgyzstan are among the few countries still mining mercury. Most global supply now comes from recycling and government stockpiles to limit environmental release.

History: Known to ancient Chinese, Egyptians, and Hindus. Named after the Roman god Mercury; symbol Hg from Latin "hydrargyrum" (liquid silver). Alchemists believed it was the First Matter from which all metals were formed.

Health Effects & Safety: Highly toxic heavy metal. Inhalation of vapor affects nervous, digestive, and immune systems, lungs and kidneys. Organic mercury (methylmercury) bioaccumulates in fish and causes Minamata disease.

Price/Market: Low price due to restricted use and surplus supply from decommissioning industrial plants. Trade is heavily regulated by international treaties (Minamata Convention).

Properties: Liquid at room temperature (freezes at -38.8°C), high surface tension, forms amalgams with many metals (except iron), high density (13.5 g/cm³), and fair electrical conductor.
