Question

Quizplus · Accepted Answer

Potassium (K) is the most similar to sodium (Na) in chemical and physical properties. This is because they both belong to the same group (Group 1 or alkali metals) of the periodic table and have similar electronic configurations. Like sodium, potassium is a soft, silvery metal that reacts violently with water to form alkaline solutions. In addition, both sodium and potassium ions are important in nerve impulse transmission and muscle function in living organisms.
