Column 1 has 1 e- in outer ring, element gives away 1 e-
column 2 has 2 e- in outer ring, elememt gives away 2 e-
column 6/16 has 6 e- outer ring, element takes 2 to make 8
column 7/17 has 7 e-, element takes 1 e- to make 8
column 8/18 has 8 e- in valence ring, it is stable
The periodic table is arranged into columns with the same number of valence electrons because these elements react similarly.

All elements in the same group have similar valence electron structures, as it is the valence electron structure that determines the chemical properties of the elements.

Elements in vertical columns have identical electron configurations of valence electrons. For example, in Group IIA, the valence electrons are 1s2, 2s2, 3s2, 4s2, 5s2, 6s2,and 7s2.

They are electrons relatively easily available to chemical bonding.
