Elements are arranged on the periodic table based on their atomic number, which is the number of protons in their nucleus. This arrangement groups elements with similar properties in columns called groups or families, while elements in the same period have the same number of electron shells.
Newland arranged all the then known elements into seven groups in his 'law of octaves'
