About

The Periodic Table is the cornerstone of modern chemistry, organizing all known elements based on their atomic structure and chemical properties. This interactive tool goes beyond a static chart, offering students, researchers, and enthusiasts a dynamic way to explore elemental data.

Whether you are calculating molar masses, studying electron configurations, or visualizing how temperature affects the state of matter, this tool provides a comprehensive database of all 118 elements. It highlights periodic trends and classifies elements into groups such as Alkali Metals, Noble Gases, and Transition Metals, making complex chemical data accessible and engaging.

Atomic Radius	Decreases	Increases
Ionization Energy	Increases	Decreases
Electronegativity	Increases	Decreases
Electron Affinity	Increases (generally)	Decreases (generally)
Metallic Character	Decreases	Increases

Frequently Asked Questions

Some superheavy elements (like Oganesson) are highly unstable and decay in fractions of a second, making it impossible to measure their macroscopic physical properties like melting points.

Changing the temperature updates the visual state of each element. Elements will appear solid, liquid, or gaseous based on their specific phase transition points relative to the selected temperature.

They are placed below the main table to keep the chart width manageable. Chemically, they fit between Group 2 and Group 4, often considered part of Group 3.

The data uses standard atomic weights recommended by IUPAC. For radioactive elements with no stable isotopes, the mass number of the most stable isotope is usually cited.
