Interactive periodic table with up-to-date element property data collected from authoritative sources. Look up chemical element names, symbols, atomic masses and other properties, visualize trends, or even test your elements knowledge by playing a periodic table game!
The periodic table isn’t just a list of elements—it’s a map of predictable patterns called periodic trends. These trends, like atomic radius, electronegativity, and ionization energy, help scientists ...
The periodic table is part of the bedrock of chemistry education. Students use it to look up values like an element’s atomic mass, and it serves as a visual reference for the trends in physical ...
The PubChem Periodic Table provides three distinct views. Table View is the traditional periodic table any scientist would instantly recognize. List View provides a summary view, allowing you to see all properties available for each element at once. Game View, added as an educational feature, helps test your knowledge of element names and symbols.
Explore how electronegativity changes with atomic number in the periodic table of elements via interactive plots.
Explore how atomic mass changes with atomic number in the periodic table of elements via interactive plots.
This lesson utilizes an adaptation of the board game Periodic: A Game of the Elements to help students better understand both general periodic trends and the law of conservation of energy. This ...
The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic ...
The Conversation: Periodic table: scientists propose new way of ordering the elements
The periodic table of the elements, principally created by the Russian chemist, Dmitry Mendeleev (1834-1907), celebrated its 150th anniversary last year. It would be hard to overstate its importance ...
