WebWhen we apply the term “reactive” to metals, we usually mean “electropositive” or “highly-reducing”. In this sense potassium or cesium are highly reactive — they react explosively with water. In contrast, gold and platinum are unreactive. WebThe most reactive nonmetal is fluorine. Fluorine is a halogen, which is Group 17 on the periodic table, and the halogens are the most reactive...
