Each horizontal row of elements is called a(n) 16. Each vertical column is called a(n) 9, or , because of the resemblance between elements in the same column, a(n) 8. In rows 4 through 7, there is a wide central section containing elements, each of which is called a(n) 20.

The horizontal rows are known as periods and vertical columns in the periodic table are known as groups. Periodicity is observed due to the similar electronic configuration.. (i) Though the number of shells remain the same, number of valence electrons increases by one, as we move across any given period from left to right.
