There is no unique and fully consistent way to define the reactivity series, but it is common to use the three types of reaction listed below, many of which can be performed in a high-school laboratory (at least as demonstrations). The most reactive metals, such as sodium, will react with cold water to produce hydrogen and the metal hydroxide: WebAs an element, phosphorus exists in two major forms—white phosphorus and red phosphorus—but because it is highly reactive, phosphorus is never found as a free …

In fact, reactivity in chemistry is defined by the number of electrons in the outermost shell. Noble gases (elements like neon and helium) are very unreactive because their outermost electron shells are full. opd cuyahoga county
