- A non-metal is an element on the periodic table that does not have the properties of a metallic element, such as malleability.Nonmetals are usually found in nature as gases or weak, brittle solids.cetate is not any single substance, but a group or ion found in certain esters and salts. It is composed of the nonmetals hydrogen, oxygen and carbon. Because it is not an … element it cannot properly be considered a metal or a nonmetal.

nonmetal General Chemistry Dictionary. (metal,metalloid) A nonmetal is a substance that conducts heat and electricity poorly, is brittle or waxy or gaseous, and cannot be hammered into sheets or drawn into wire. Nonmetals gain electrons easily to form anions . About 20% of the known chemical elements are nonmetals.

- Nonmetal elements are located to the right of the Periodic Table. All elements in Groups 17 and 18 are classified as nonmetals. The rest of the nonmetals are located near. the bottom of Group 14, 15, and 16. Hydrogen (in Group 1) is also a nonmetal. Below are some general properties (characteristics) of 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.The elements can be classified as metals, nonmetals, or metalloids.etals are good conductors of heat and electricity, and are malleable (they can be hammered into sheets) and ductile (they can be drawn into wire). Most of the metals are solids at room temperature, with a characteristic silvery shine (except for mercury, which is a liquid).

- Answers. Best Answer: PROPERTIES: Metals are shiny, are usually malleable and ductile, conducts heat and electricity, and usually solid (except mercury, which is a liquid). Nonmetals can be solid, liquid or gases and they conduct heat and electricity poorly.Solids are dull and brittle. Metalloids have properties in between metals and nonmetals.USES: The uses varies greatly depending on the element. For example, aluminum is used for creating cans to store food, as well as the outer shell of airplanes.onmetals can be solid, liquid or gases and they conduct heat and electricity poorly. Solids are dull and brittle. Metalloids have properties in between metals and nonmetals.

The Periodic Table: Metals, Nonmetals, and Metalloids Using the periodic table, you can classify the elements in many ways. One useful way is by metals, nonmetals, and metalloids. Most of the elements on the periodic table are classified as metals.onmetals have properties opposite those of the metals. The nonmetals are brittle, not malleable or ductile, poor conductors of both heat and electricity, and tend to gain electrons in chemical reactions. Some nonmetals are liquids.

Wikipedia:Reference desk archive/Humanities/April 2006 There are a few properties which can be used to tell metals and nonmetals apart: Luster (i.e. shininess): If you see something that's shiny in a metallic sort of way, it's probably a metal. Electrical conductivity: If something conducts electricity as a solid, it's probably a metal. State of matter: If it's a gas at room temperature, it's not a metal.

Properties of metals, metalloids and nonmetals Metalloids are metallic-looking brittle solids that are either semiconductors or exist in semiconducting forms, and have amphoteric or weakly acidic oxides. Typical nonmetals have a dull, coloured or colourless appearance; are brittle when solid; are poor conductors of heat and electricity; and have acidic oxides.

NON-METAL ELEMENTS The metal elements in the periodic table have easily defined properties. The remaining elements, however, have very different properties. They consist of a group of unreactive gases called the NOBLE GASES, a group of reactive elements known as the HALOGENS, and a set of elements referred to as non-metals.In addition, a few elements have properties that place them in between metals and non-metals. They are called the SEMI-METALS.he remaining elements, however, have very different properties.

What Is a Nonmetal in Chemistry? Quick Answer. A nonmetal element in chemistry is an element that does not possess the properties of metals, and is found in the groups 14, 15 and 16 of the periodic table. Unlike metals, nonmetals are poor conductors and typically have more than four valence electrons. Continue Reading.

HOME TheInfoList.com physically nonmetals tend to be highly volatile easily vaporized have low elasticity and are good insulators of heat and electricity chemically they tend to have high ionization energy and electronegativity values and gain or share electrons when they react with other elements or compounds

- The properties of non-metals are the opposite for those of metals. Non-metals love electrons, especially the ones they already have, which means they have high ionization energies and high electronegativities.Their large electron affinities means they have the ability to gain electrons easily.hese metals are solid, shiny, and good conductors of electricity and heat, all properties that we normally associate with metals. They are also ductile and malleable, which means they can be drawn into thin wires and hammered into thin sheets.
