What form of the periodic table labels families 1-18 in Arabic numerals?

What form of the periodic table labels families 1-18 in Arabic numerals?

• A. IUPAC Periodic Table
• B. North American Convention Periodic Table
• C. European Convention Periodic Table
• D. Standard Periodic Table

Answer: (A)

The IUPAC Periodic Table is recognized for labeling the groups or families of elements using Arabic numerals from 1 to 18. This system provides a standardized way to identify the vertical columns in the periodic table, which is important for understanding the relationships and characteristics of elements within the same group. Each numbered group shares similar properties due to their valence electron configurations, making it easier to predict chemical behavior and reactivity. This modern approach is widely accepted in scientific literature and education, ensuring clarity and consistency across different regions and educational materials. The other naming conventions may use different systems, such as Roman numerals or a mix of formats, which can lead to confusion in communication about the periodic table of elements.
