chromium, calcium, and potassium are near each other on the periodic table and have some common characteristics but differ in chemical reactivity. which lists these metals in order from most reactive to least reactive?\ncalcium, chromium, potassium\nchromium, calcium, potassium\npotassium, calcium, chromium\npotassium, chromium, calcium
Answer
Brief Explanations:
In the periodic table, the reactivity of metals generally increases down a group and decreases across a period from left - to - right. Potassium is an alkali metal in Group 1, calcium is an alkaline - earth metal in Group 2, and chromium is a transition metal. Alkali metals are highly reactive, followed by alkaline - earth metals, and transition metals are less reactive compared to the first two.
Answer:
C. potassium, calcium, chromium
