all elements in each column share similar properties, as do all of the elements in each row. also, they are ordered by the number of protons in their nucleus

Elements in columns are often referred to as "families". They have similar chemical and physical properties.
Elements in a row have their outermost electrons in the same energy level. Row 1 elements use level 1 (which can only hold 2 electrons so there are only 2 elements in the first row).
Elements in row 2 have filled their 1st level and are working on filling the 2nd level.......etc.

It has to do with complete and incomplete groupings of electrons. The Inert elements have all the spaces for electrons filled. The elements in between have space to bond more easily with other elements.

All aspects in an analogous group have comparable properties and style of valence electrons, all aspects in an analogous era have the valence electrons in an analogous potential point
