The metalloids fall in between, near. the zigzag line. This trend isnât a coincidence. The number of valence electrons, or electrons in the. outer shell, determines how an element acts. For example, metals have few electrons in their outer shell. This causes them to possess metallic properties such as, conductivity & reactivity. Conversely, the. nonmetals on the right of the periodic table have almost complete sets of electrons in their outer level.
