the simplest definition of non metals is that it is an element or substance that is not a metal.

examples of non-metals are : Hydrogen, hydrogen, chlorine, fluorine, carbon, nitrogen, phosphorus, selenium .

characteristics of non metals

the following are characteristics of non metals:

Form Covalent/Ionic Bonds. One of the primary characteristics of nonmetals is that they form chemical compounds by making covalent and ionic bonds

Brittle.

Low Melting/Boiling Points.

High Ionization Energy/Electronegativity.

they are Poor Conductors Of Heat And Electricity.

Nonmetals, which are found in the right-hand region of the periodic table, have relatively large ionization energies and therefore tend to gain electrons and The reason why non metals gain electrons in order to achieve a full stable outer shell. therefore, non-metals end up gaining electrons because they have more valence electrons than metals, so make a stable octet, it is easier for them to gain electrons rather than lose them.

facts about non metals

Elements that are nonmetals are hydrogen, carbon, nitrogen, phosphorus, oxygen, sulfur, selenium, all of the halogens, and the noble gases. Nonmetal Physical Properties: May be solids, liquids or gases at room temperature. Transparent as a thin sheet.

In general, non-metals are brittle, dull, and poor conductors of heat and electricity. They are most likely to have lower melting points than metals. Most of non-metals exist in two of the three states of matter at room temperature: gases and solids, except bromine, which exists as a liquid.

Period 2 only has two metals (lithium and beryllium) of eight elements, less than for any subsequent period both by number and by proportion. It also has the most number of nonmetals, namely five, among all periods.

there are Seventeen elements generally classified as nonmetals; mostly gases (hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon); one is a liquid (bromine); and a few are solids (carbon, phosphorus, sulfur, selenium, and iodine).

Five times more elements are metals than nonmetals. Two of the nonmetals and make up over 99 percent of the observable , and one makes up close to half of the earths crust , atmosphere and oceans .

most materials are capable of becoming metallic if put under enough pressure. Atoms or molecules can be squeezed together so tightly that they begin to share their outer electrons, which can then travel and conduct electricity as they do in a chunk of copper or iron. Geophysicists think that the centers of massive planets such as Neptune or Uranus host water in such a metallic state, and that high-pressure can even , able to conduct electricity without any resistance.

Although new metals are being produced and some metals were difficult to isolate in pure form, there were seven metals known to ancient man. These were :gold, copper, silver, mercury, lead, tin, and iron.
