State
Metallic character is the tendency to lose valence electrons readily; it rises as ionization energy falls, down a group and leftward across a period.
Show
Cesium, far down and left, loses its valence electron more easily than any other stable element.
Watch for
Metallic character is a matter of degree, not a fixed label; metalloids sit where the trend crosses from metallic to nonmetallic behavior.
