Because of periodic trends, we can predict, at least in a general sense, the properties of elements. With this in mind, what is the difference between metallic and nonmetallic elements, such as their physical and chemical properties? Is there any easy way or trick to memorizing/thinking about the differences?
Metallic elements generally have properties intermediate between those of metals and nonmetals such as silicon and boron. Nonmetals on the other hand do not exhibit metallic properties. They are gases located generally in the upper right hand corner of the periodic table.
Metallic elements tend to be lustrous, ductile, malleable, can conduct electricity, and tend to form cations in aqueous solutions. Nonmetals are non-lustrous, brittle, poor conductors, and tend to form anions in solutions.
