검증된 단계별 안내1
Understand the structure of the periodic table: it is organized into rows and columns.
Identify that the horizontal rows in the periodic table are called 'Periods'.
Recognize that the vertical columns in the periodic table are called 'Groups' or sometimes 'Families'.
Note that 'Blocks' refer to sections of the periodic table based on electron configurations (s, p, d, f blocks), not columns.
Therefore, the term used to describe the vertical columns on the periodic table is 'Groups'.
