Understand that the periodic table is organized in two main directions: horizontally and vertically.
Recognize that the horizontal rows in the periodic table are called 'Periods'. Each period corresponds to the filling of a different electron shell.
Know that the vertical columns are called 'Groups' or 'Families', which contain elements with similar chemical properties.
Identify that 'Blocks' refer to sections of the periodic table based on electron subshells (s, p, d, f), not rows or columns.
Therefore, the correct term for the horizontal rows in the periodic table is 'Periods'.
