Question

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? calcium, chromium, potassium chromium, calcium, potassium potassium, calcium, chromium potassium, chromium, calcium

Explanation:

In the activity series of metals, potassium (\(K\)) is highly reactive. Calcium (\(Ca\)) is also reactive but less than potassium. Chromium (\(Cr\)) is relatively less reactive among these three. So, based on the reactivity series of metals.

Answer:

potassium, calcium, chromium (the third option)
