“I call it the bicycle-wheel periodic table,” Dr. Scerri said. Lothar Meyer, a German chemist, created a partial periodic table in 1864, and a more complete version in 1869.

The periodic table is an icon. But chemists still can’t agree on how to arrange it New data about the elements and their relationships have led to debate over the 150-year-old table’s optimum ...

Why has the periodic table endured for 150 years? It’s an amazing tool that can compress a huge amount of information into one format. It’s one of the first things people learn about chemistry.

So the beauty of the periodic table is that the elements that are in columns, up and down, have similar properties. But there are similarities within a group going across too.
