An interactive periodic table of all 118 chemical elements, made for students. Open any element to see its atomic mass, electron configuration, melting and boiling points, density, electronegativity, ionization energy and oxidation states, each with a short explanation.
Colour the table by category or by a property to see the periodic trends: how electronegativity rises towards fluorine, or how atoms grow larger down each group.
