Nonmetals have properties opposite those of the metals. Nonmetal elements don t form positive ions nor do they possess metallic bonds.

The periodic table of metals and nonmetals can be broken down to give you a sense of each element s characteristics.

Elements metal or nonmetal. The nonmetal element group consists of hydrogen carbon nitrogen oxygen phosphorus sulfur and selenium. At ordinary temperatures and pressures hydrogen behaves as a nonmetal. The nonmetals are brittle not malleable or ductile poor conductors of both heat and electricity.

Examples of nonmetal elements include hydrogen helium nitrogen oxygen fluorine chlorine sulfur argon xenon radon and phosphorus. Elements just to the right of the line exhibit properties of both metals and nonmetals and are termed metalloids or semimetals. Metals nonmetals and metalloids make up the periodic table with metals constituting the large majority of all metals.

Hydrogen acts as a nonmetal at normal temperatures and pressure and is generally accepted to be part of the nonmetal group. The nonmetals or non metals are a group of elements located on the right side of the periodic table except for hydrogen which is on the top left. Except for the elements that border the stair stepped line the elements to the right of the line are classified as nonmetals along with hydrogen.

The periodic table contains a lot of useful information on the elements. A nonmetal element on the other hand is an element that lacks the characteristics of its metal counterparts. The exception is hydrogen h the first element on the periodic table.

These elements and those to the right of them are nonmetals. When elements combine to form compounds there are two major types of bonding that can result. 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. Most elements are metals. The nonmetal element group is a subset of these elements.

These elements are distinctive in that they typically have low melting and boiling points don t conduct heat or electricity very well and tend to have high ionization energies and electronegativity values. Elements to the far right of the periodic table are nonmetals. The metals are to the left of the line except for hydrogen which is a nonmetal the nonmetals are to the right of the line and the elements immediately adjacent to the line are the metalloids.
