검증된 단계별 안내1
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'.
Identify that the vertical columns in the periodic table are called 'Groups' or 'Families'.
Know that elements in the same group share similar chemical properties because they have the same number of valence electrons.
Therefore, the correct term for a vertical column in the periodic table is 'Group' (also called a family).
