Calcium is a moderately active element. It reacts readily with oxygen to form calcium oxide (CaO): Calcium reacts with the halogens— fluorine, chlorine, bromine, iodine, and astatine, The halogens are the elements that make up Group 17 (VIIA) of the periodic table. Calcium also reacts readily with cold water, most acids, and most nonmetals, such

Potassium, Chemical Element - reaction, water, uses, …

The skipping is caused by hydrogen gas produced in the reaction pushing the metal around. The potassium would soon ch fire, burn, and, perhaps, explode. Potassium reacts readily with all acids and with all non-metals, such as sulfur, chlorine, fluorine, phosphorus, and nitrogen.

Properties of Metals Science Lesson | HST Learning Center

This happens when oxygen (usually from the air) reacts with a metal. Metals with a higher reactivity (such as magnesium, aluminum, iron, zinc, and tin) are much more prone to this kind of chemical destruction, or corrosion. When oxygen reacts with a metal, it forms an oxide on the surface of the metal.
