Verified step by step guidance1
Understand that the periodic table is organized in two main directions: horizontally and vertically.
Recognize that the vertical columns in the periodic table are called 'Groups' or 'Families', which contain elements with similar chemical properties.
Know that the horizontal rows in the periodic table are called 'Periods'. Each period represents elements with the same number of electron shells.
Be aware that 'Block' refers to sections of the periodic table based on electron subshells (s, p, d, f blocks), not rows or columns.
Therefore, the term for a horizontal row in the periodic table is 'Period'.
