The most important principle was the listing in groups, after similar chemical or physical properties.
In the periodic table, the elements are grouped according to their properties. Elements in a group has an equal number of valence electrons. So the elements in a group have most common chemical properties.
The columns on The Periodic Table are called groups. All elements in the same group share characteristics such as reactivity toward other substances. Also, elements in the same group contain the same amount of electrons in the outer shell of their atoms.
