Final answer:
A group of elements in the periodic table with similar properties is described as those listed in the same column or group, where they share similar valence electron configurations.
Step-by-step explanation:
The group of elements in the periodic table with similar properties are best described as elements that are listed in the same column. These columns are known as groups or families, and elements within these groups share similar chemical properties. For instance, Group 1 contains the alkali metals, Group 2 includes the alkaline earth metals, Group 17 is home to the halogens, and Group 18 comprises the noble gases. The consistent properties among group members arise from their similar valence electron configurations, which dictate their chemical behaviors and reactions.
