Periodic table of elements

All 118 elements. Click an element for its description, data and a rotating 3D model of its atom – the nucleus of protons and neutrons with electrons orbiting in shells. Search by name, symbol or atomic number, or filter by category.

Data: Periodic-Table-JSON (Bowserinator); descriptions from Wikipedia (CC BY-SA). The atom model is not to scale – a real nucleus is about 100,000 times smaller than the atom.
