Periodicity is one of the most fundamental aspects of the table of the elements. Here is an explanation of what it is and a look at the properties.
The most reactive metal on the periodic table is francium. Francium, however, is a laboratory-produced element and only minute quantities have been made, so for all practical purposes, the most reactive metal is cesium. Cesium reacts explosively with water, though it is predicted francium would...
