What is an interactive periodic table?

An interactive periodic table is a digital version of the periodic table of elements that allows users to click on elements to view detailed information, visualize trends, compare elements, and explore atomic properties. Our interactive periodic table includes all 118 elements with comprehensive data including atomic mass, electron configurations, electronegativity, melting/boiling points, atomic radius, ionization energy, and visual Bohr model diagrams.

How do I use the periodic trends visualization?

Select a trend from the 'Color by' dropdown menu: Atomic Radius (shows size trends), Electronegativity (shows electron attraction), or Ionization Energy (shows energy to remove electrons). Elements are color-coded from red (low values) to blue (high values) to visualize periodic patterns. You can also view trends by element category, state at temperature, electron block, or periodic group.

How do I compare two elements?

Click the 'Compare Elements' button, then select any two elements by clicking on them. A comparison panel will automatically appear showing side-by-side properties including atomic mass, electronegativity, melting/boiling points, atomic radius, and ionization energy. Higher values are highlighted in green for easy comparison.

What is the Bohr model electron shell diagram?

The Bohr model shows electrons arranged in shells (energy levels) around the nucleus. When you click any element, scroll down to see its Bohr diagram showing the nucleus with the element symbol and electrons distributed in shells following the 2, 8, 18, 32 electron capacity pattern. Each shell is labeled with its principal quantum number (n=1, 2, 3...) and electron count.

Can I use keyboard shortcuts to navigate the periodic table?

Yes! Use arrow keys (↑↓←→) to navigate between elements, Enter to select an element, ESC to close details, C to toggle comparison mode, and ? to show/hide the keyboard shortcuts help panel. The focused element is highlighted with a blue outline.

What element properties are shown?

Each element displays 14 properties: atomic number, symbol, name, atomic mass, category (metal/nonmetal/etc), electron configuration, group and period, electron block, melting point, boiling point, electronegativity, oxidation states, discovery year, state at 25°C, atomic radius (pm), and ionization energy (kJ/mol).

Is the periodic table mobile-friendly?

Yes, the interactive periodic table is fully responsive and works on all devices. On mobile devices, you can scroll horizontally to view all elements. A scroll hint appears on smaller screens to guide you. All features including element details, comparison mode, and electron shell diagrams work on mobile.

What are periodic trends?

Periodic trends are patterns in element properties that repeat across periods and down groups. Major trends include: Atomic Radius (increases down groups, decreases across periods), Electronegativity (decreases down groups, increases across periods), and Ionization Energy (decreases down groups, increases across periods). Our visualization uses color gradients to make these trends instantly visible.
