Which Elements Are Covalent? | Sciencing Covalent bonds are chemical bonds in which two or more elements join together by sharing electrons, rather than transferring electrons, as is the case with ionic bonds. These bonds tend to occur with nonmetal elements of the periodic table. Which Is The Most Reactive Element In The Periodic Table ... Fluorine is identified as the most electronegative element in the periodic table, making it the strongest reducing agent. It is the most reactive non-metal. Caesium is the most reactive metal in the periodic table, so much that working with this metal often ends in explosions! Read More
Nonmetal - Simple English Wikipedia, the free encyclopedia
Nonmetal or non-metal is a chemical element that does not have the properties of a metal. Some are gases including: hydrogen, helium, oxygen, nitrogen, fluorine, neon, or radon and many others. An example of a solid that is a nonmetal is sulfur. It is yellow and not shiny at all. An example of a liquid that is a nonmetal is bromine. It is red.
DMOZ - Science: Chemistry: Elements: Nonmetals
Welcome to the home of NonmetalS! Nonmetal elements possess high ionization energies and have high electronegativities. They tend to gain electrons when in combination with metals, or to share electrons when in combination with other elements. They tend to be brittle in the solid phase, to have low thermal and electrical conductivities, and to lack metallic luster.
Difference Between Metals and Nonmetals
Metals vs Nonmetals Both metals and nonmetals may be part of the periodic table but there is a lot of differences between metal and nonmetals in both chemical and physical make-up. Most of the elements in the periodic table are metals and only a few are nonmetals. These elements are arranged in the table by their electronic structure.
Metals and Nonmetals - Chemistry | Socratic
Metals, Nonmetals, and Metalloids are three classes of elements. The majority of elements in the periodic table are metals which are characterized by being shiny and solid (except Mercury) yet still malleable (or able to be molded and shaped). Metals are excellent conductors of electricity and heat.
What are some examples of nonmetals and their uses? - Quora
There also some Metalloid elements like arsenic and antinomy that have both metal and non metal characteristics. Non metals physically lack the ductility and lustre of metals. But the main chemical difference is that metals form positive ions by losing electrons in reaction and non-metals gain electrons to form negative ions.

Which element is an active nonmetal? | Yahoo Answers
Jan 03, 2013· Best Answer: ANS='C' The terms metal and nonmetal are really descriptive of ways atoms react; metals lose electrons, nonmetal gain them. Another category of atom is a noble gas - atoms that already have the full valence shell that metals and nonmetal react to acquire.
Nonmetals: Quick Chemistry Facts
Nonmetals: Unlike metals, which are electrically and heat conductive, nearly all nonmetals are either insulators or semiconductors and poor conductors of heat. Non-metals are usually unreactive. They can be either solid, liquid or gas. Their solid forms are more commonly brittle and not ductile like metals.

Ionic Compounds - Department of Chemistry
In crystalline compounds this net balance of forces is called the LATTICE ENERGY. Lattice energy is the energy released in the formation of an ionic compound. DEFINITION: The formation of an IONIC BOND is the result of the transfer of one or more electrons from a metal onto a non-metal.
What is the most reactive nonmetal? | Yahoo Answers
Oct 12, 2006· 1. It is at the right hand end of its row of the Periodic Table, which means it has the biggest nucleus and more protons than any element in that row. Protons are positive and attract electrons, which are negative. It is the most attractive and therefore most reactive non-metal element in .
Metals, Nonmetals, & Metalloids - Windows to the Universe
The periodic table on the left separates elements into three groups: the metals (green in the table), nonmetals (orange), and metalloids (blue). Most elements are metals . They are usually shiny, very dense, and only melt at high temperatures.
What element is a nonmetal - science.answers
Nonmetal element is one of the elements which do not exhibit metallic properties, generally located in the upper right hand corner of the Periodic Table. 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.
