Nonmetals, with the exception of hydrogen, are located on the right side of the periodic table. Elements that are nonmetals are hydrogen, carbon, nitrogen, phosphorus, oxygen, sulfur, selenium, all of the halogens, and the noble gases.
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.

Metals, except mercury & gallium are solids at room temperature while non-metals , except bromine are solids or gases at room temperature. Metals are lustrous while non-metals, except diamond & graphite which are allotropes of carbon as well as iodine, arenon-lustrous. Metals are good conductors of heat & electricity.

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.

* the metals are generally present in solid form at room temperature but non-metals are may be solid,liquid and gaseous
* solid is a good conductor of heat but non-metal are bad conductor of heat
*metals are lustrous i.e. having shining appearence but non-metal have dull shine.
