Periodic Table of Elements - PubChem
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!
Atomic Mass | Periodic Table of Elements - PubChem
Explore how atomic mass changes with atomic number in the periodic table of elements via interactive plots.
Atomic Radius | Periodic Table of Elements - PubChem
The atomic radius of a chemical element is a measure of the size of its atom, usually, the distance from the center of the nucleus to the outermost isolated electron. Because an atom does not have a discrete boundary, there are various non-equivalent definitions of atomic radius, such as Van der Waals radius and covalent radius.
