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

Arsenic (As) is a steel-gray, brittle, crystalline metalloid that occurs in several allotropic forms. It is notorious for its toxicity but has important industrial and technological applications. Key details about Arsenic (As) are as follows:

Uses: Used in semiconductors (gallium arsenide GaAs for high-speed electronics and optoelectronics), wood preservatives (chromated copper arsenate, CCA, now restricted), alloying agent (lead-arsenic alloys for ammunition and batteries), pesticides (now largely banned), and in some pharmaceutical applications (arsenic trioxide treats certain leukemias).

Production/Extraction: Produced mainly as arsenic trioxide (As₂O₃) from copper and lead smelting, or from arsenopyrite (FeAsS) ore. China and Morocco are major producers. Often obtained as a byproduct since dedicated arsenic mining is rare.

History: Known since ancient times; compounds used as poisons, pigments, and medicines. Elemental arsenic isolated by Albertus Magnus around 1250 CE. Name from Greek "arsenikon" (yellow orpiment mineral), itself from Arabic and Persian. Widely used in the Victorian era as a poison.

Health Effects & Safety: Highly toxic—arsenic and its compounds are carcinogenic and can cause acute poisoning (nausea, vomiting, death) or chronic poisoning (skin lesions, cancer, cardiovascular disease). Contaminated groundwater affects millions globally. Paradoxically, arsenic trioxide treats certain cancers.

Price/Market: Limited commercial market due to toxicity concerns and environmental regulations. Most applications have been phased out or restricted. Semiconductor applications continue.

Properties: Exists in gray (metallic), yellow, and black allotropes. Gray arsenic is the most stable and conducts electricity poorly. Sublimes when heated (turns directly from solid to gas at 615°C), exhibits +3 and +5 oxidation states, and forms toxic compounds.
