Nonmetals are typically poor conductors of heat and electricity, with low melting and boiling points. They tend not to be malleable or ductile, so they form brittle solids. Nonmetals include solids, liquids, and gases at room temperature and pressure.

The non-metals exist in two of the three states of matter at room temperature: gases (such as oxygen) and solids (such as carbon). The non-metals have no metallic luster, and do not reflect light. They have oxidation numbers of ±4, -3, and -2.

Non-metals are the elements which form negative ions by accepting or gaining electrons. Non-metals usually have 4, 5, 6 or 7 electrons in their outermost shell. Table of Contents.

Once the metals and semimetals are removed from the list of known elements, only 17 are left to be classified as nonmetals. Six of these elements belong to the family of rare gases in Group VIIIA, most of which are virtually inert to chemical reactions.

From a chemical point of view, nonmetals may be divided into two classes: 1) covalent materials, which contain atoms having small sizes, high electronegativities, low valence vacancy to electron ratios, and a pronounced tendency to form negative ions in chemical reactions and negative oxidation states in their compounds; 2) ionic materials, …

The nonmetal elements occupy the upper right-hand corner of the periodic table. Nonmetals include the nonmetal group, the halogens, and the noble gases. These elements have similar chemical properties to each other that distinguish them from the elements that are considered metals.

The Non-metals that are are solids are Carbon, Phosphorus, Selenium and Sulfer. The properties of non-metals are therefore not universal or as consistent as the metals. What are Non-metals? Common Properties of Solid Non-metals. Elements described as the solid Non-metals have low melting points compared to the metals.

The nonmetal elements or nonmetals are a group of elements located on the right side of the periodic table (except for hydrogen, which is on the top left).

Nonmetals are generally poor conductors of heat and electricity. Properties of nonmetals are usually the opposite of properties of metals; Nonmetals can be solid, liquid, or gas at room temperature depending upon the element. Sulfur, bromine, and helium are typical nonmetals.
