Question

question 5 of 10
what is a periodic trend?

a. any characteristic of the noble gases

b. a pattern that appears on the periodic table

c. a numbering system for the periodic table

d. an older version of the periodic table

Explanation:

To determine the correct answer, we analyze each option:

• Option A: Noble gases have specific characteristics, but periodic trends are not limited to noble gases. So A is incorrect.
• Option B: Periodic trends are patterns (like atomic radius, electronegativity, etc.) that emerge as we move across or down the periodic table. This matches the definition.
• Option C: A numbering system (like group/period numbering) is not what a periodic trend is. So C is incorrect.
• Option D: Periodic trends are not related to an older version of the periodic table. So D is incorrect.

Answer:

B. A pattern that appears on the periodic table
