Which of these elements exhibits chemical behavior similar to that of potassium?
A) magnesium
B) sodium
C) sulfur
D) chlorine
E) iron

Question

Quizplus · Accepted Answer

Sodium exhibits chemical behavior similar to that of potassium as they both belong to the same group (Group 1 or alkali metals) in the periodic table and have similar valence electron configurations. Magnesium and iron belong to Group 2 and Group 8 respectively and have different valence electron configurations, making their chemical behavior different. Sulfur and chlorine belong to Group 16 and Group 17 respectively, and have significantly different properties due to their electronegativity and valence electron configurations.
