Answer:
Most elements are metals. This includes the alkali metals, alkaline earth metals, transition metals, lanthanides, and actinides. On the periodic table, metals are separated from nonmetals by a zig-zag line stepping through carbon, phosphorus, selenium, iodine, and radon. These elements and those to the right of them are nonmetals. Elements just to the left of the line may be termed metalloids or semimetals and have properties intermediate between those of the metals and nonmetals. The physical and chemical properties of the metals and nonmetals may be used to tell them apart.
Nonmetals are found on the right side of the periodic table, with the exception of hydrogen. Hydrogen, carbon, nitrogen, phosphorus, oxygen, sulfur, selenium, all of the halogens, and the noble gases are nonmetal elements.
