Question

Revolt · Accepted Answer

All elements in group 13 have 3 valence electrons.; Losing electrons during chemical reactions causes metallic behavior in elements.; It is easier to lose 3 electrons than it is to gain 5, so most group 13 elements behave as metals.; Having fewer electron shells makes it easier to gain electrons.; Boron has so few electron shells that it is just as easy for it to lose electrons as it is to gain electrons, so it behaves like a metalloid.
