Verified step by step guidance1
Understand that the periodic table is organized in two main directions: horizontally and vertically.
Rows in the periodic table run horizontally from left to right and are called 'Periods'.
Columns in the periodic table run vertically and are called 'Groups' or 'Families'.
Blocks refer to sections of the periodic table based on electron configurations (s, p, d, f blocks), not rows or columns.
Therefore, the correct term for the horizontal rows is 'Periods'.
