The chemical elements can be broadly divided into metals, metalloids and nonmetals according to their shared physical and chemical properties. All metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metals; and have at least one basic oxide.

Metals like sodium (Na) and potassium (K) are some of the most reactive metals. Potassium, sodium, lithium, calcium and magnesium react with oxygen and burn in air.

Both, metals and nonmetals, have differences in both chemical and physical properties. Metals are great conductors of electricity and heat and when subjected to chemical changes they loose electrons and become cations. Also, metals are solid at room temperature and are flexible and stretchable.

What are the Nonmetals? More than 75% of the known elements have the characteristic properties of metals (see figure below). They have a metallic luster; they are malleable and ductile; and they conduct heat and electricity. Eight other elements (B, Si, Ge, As, Sb, Te, Po, and At) are best described as semimetals or metalloids

Nonmetal, substance that does not exhibit such characteristic properties of metals as hardness, mechanical adaptability, or the ability to conduct electricity. This classification is generally applied to the chemical elements carbon, nitrogen, phosphorus, oxygen, sulfur, selenium, fluorine, chlorine, bromine, iodine, and the noblegas elements.

METALS, NONMETALS, AND METALLOIDS A diagonal line of elements separates the metals from the nonmetals. These are called metalloids. The metalloids—elements like boron, silicon, and antimony—have some properties of metals and other properties of nonmetals. When you think of nonmetals, you might think of materials made of plastic .

The highlighted elements are the nonmetal elements. The nonmetal elements occupy the upper righthand corner of the periodic table. These elements have similar chemical properties that differ from the elements considered metals. The nonmetal element group is a subset of these elements.

Elements that have properties of both metals and nonmetals are called metalloids. They can be shiny or dull and their shape is easily changed. Electricity and heat can travel through metalloids but not as easily as they travel through metals.

Nonmetals, as their name implies, are elements that display properties quite different from those of metals. Generally, they are poor conductors of heat and electricity, and they are not ductile: in other words, they cannot be easily reshaped.
