In 1992, with a handful of web pages populating the new World Wide Web, a graduate student at Los Alamos National Laboratory did something extraordinary: he launched one of the very first interactive periodic table of elements – and it still exists today.

The items on the table are clickable, giving users – mostly elementary, middle and high school students working on chemistry homework – the chance to delve into everything there is to know about them, from their backgrounds and properties to their electron configurations and boiling. points.

Over the years, experts from the Laboratory’s Chemistry Division have enriched the periodic table a few times with facelifts and redesigns. The table was last updated in 2016 to include four new elements: nihonium (Nh, element 113), moscovium (Mc, element 115), tennessine (Ts, element 117) and oganesson (Og, element 118) .

Some 30 years after its launch, the chart is still racking up hundreds of thousands of views each year, proving that it is still an incredibly popular and valued resource in the chemistry world.
