steel atoms shed some of their valence electrons through a procedure called oxidation, bring about a big variety the ionic compounds consisting of salts, sulfides and oxides. The properties of metals, an unified with the chemical action of other elements, results in the carry of electron from one atom come another. Although few of these reactions have undesirable results, such together corrosion, batteries and other advantageous devices also depend top top this type of chemistry.

You are watching: What happens to metals when they form an ion


One of the distinguishing features of steel atoms is the looseness that their external electrons; due to the fact that of this, metals are typically lustrous, an excellent conductors the electricity, and can be formed and shaped fairly easily. Through contrast, non-metals such as oxygen and sulfur have tightly-bound electrons; these elements are electrical insulators and also brittle together solids. Because of the looseness the the electrons neighboring metals, other elements “steal” lock to type stable chemical compounds.


The octet dominion is a principle supplied by chemists to identify the proportions in i beg your pardon atoms integrate to form chemical compounds. Merely put, many atoms become chemically stable when they have actually eight valence electrons; however, in their neutral state, they have actually fewer than eight. An aspect such together chlorine, because that example, is normally missing one electron, yet noble gases such as neon have the full complement, for this reason they rarely integrate with various other elements. For chlorine to become stable, it have the right to remove an electron from a surrounding sodium atom, creating sodium chloride salt in the process.


The chemical process of oxidation and reduction describes how non-metals remove electrons from metals. Metals shed electrons and thereby end up being oxidized; non-metals get electrons and become reduced. Relying on the element, a metal atom deserve to lose one, 2 or three electrons come one or much more non-metals. Alkali metals such as sodium shed one electron, vice versa, copper and iron may shed up to three, depending upon the reaction.

Ionic compounds room molecules that kind through the gain and loss the electrons. A steel atom the loses an electron bring away on a positive electrical charge; a non-metal the gains an electron i do not care negatively charged. Due to the fact that opposite charges attract, the two atoms rod together, forming a strong, steady chemical bond. Examples of ionic compounds incorporate snow-melting salt, calcium chloride; rust, which combines iron and oxygen; copper oxide, the greenish corrosion that creates on buildings and also sculptures -- and lead sulfate, a compound supplied in car batteries.
