A) Rows
B) Sections
C) Periods
D) Groups or Families
Correct Answer:
D) Groups or Families
Explanation:
The vertical columns of the periodic table are called “groups” or “families.” Each group contains elements with similar chemical properties due to their shared electron configurations. Rows in the periodic table are known as “periods.” Option B (“Sections”) and option C (“Periods”) refer to other aspects of the periodic table but are not specifically related to the vertical columns.
