John Newlands compared elements to musical notes with his law of octaves. As on a scale, every eighth element would share similar properties when arranged by increasing atomic weight. Newlands did not account for exceptions, however, and it was only upon establishment of the Periodic Table that...

Explanation of the structure of the periodic table The number of electron shells an atom has determines what period it belongs to. Each shell is divided into different subshells, which as atomic number increases are filled in roughly this order: 1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f ...
While at YGLF I discovered that a couple days prior to posting this Chen Hui Jing had made her own periodic table grid experiment — but with HTML elements instead of chemical elements. Similar but different. It is worth comparing the two approaches just to see the variety of techniques. ...
