Use the following image to determine which statement is true: Calcium is the most reactive because it has the most energy levels (shells.)   Carbon is the most reactive because it can take or give 4 electrons.   Helium is the most reactive because it is the simplest and can therefor react easier.   Lithium is the most reactive because it has a valence of 1.
