In Modern periodic table, in a group, the outermost electronic configuration is identical. All the elements in a group have the same number of valence electrons but the number of shells increases as we move down the group.
In a period, the elements do not have same number of valence electrons but the number of valence electrons increase by one unit as the atomic number increases by one unit on moving from left to right in the modern periodic table. The elements of the same period have the same number of shells.
