The most reactive metals like potassium, sodium and magnesium will burn with a very bright flame and will tarnish quickly in open air. Moderately reactive metals such as magnesium, aluminium, zinc and iron burn in strong flame but don''t tarnish rapidly in open air.
Calcium - Compounds | Britannica
Calcium - Calcium - Compounds: The most important calcium compound is calcium carbonate, CaCO3, the major constituent of limestone, marble, chalk, oyster shells, and corals. Calcium carbonate obtained from its natural sources is used as a filler in a variety of products, such as ceramics, glass, plastics, and paint, and as a starting material for the production of calcium oxide. Synthetic
Potassium chloride - Wikipedia
Potassium chloride (also known as KCl or potassium salt) is a metal halide salt composed of potassium and chlorine. It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water, and its solutions have a salt -like taste.

Reactivity Series - Reactivity of Metals Chart, Features, Uses
Calcium and the metals that are more reactive than calcium in the reactivity series can react with cold water to form the corresponding hydroxide while liberating hydrogen gas. For example, the reaction between potassium and water yields potassium hydroxide and H 2 gas, as described by the chemical equation provided below.
