An ionic compound is a substance formed from the chemical binding of elements with opposite charges. The force of attraction between opposite charges keeps the molecule together. Common table salt, or sodium chloride, is an example of an ionic compound.Continue Reading
Elmhurst College's Virtual Chembook explains that the main players in ionic compounds are the ions, which are charged atoms. Atoms form ions because ions are usually more stable than the neutral atom. The most stable arrangement for an atom is to have eight valence electrons in its outermost energy level. Most elements on the periodic table do not have this electron configuration. Depending on how many valence electrons it has, an atom gains or loses electrons. Atoms that have relatively few valence electrons, such as metals, lose electrons and are electropositive. Atoms that contain six or seven valence electrons, such as nonmetals, attract more electrons and are electronegative. Once an atom gains or loses electrons, it possesses a charge and becomes an ion. Ions have different properties from the neutral forms of the atoms.
When an electropositive atom meets up with an electronegative atom, electrons jump from the electropositive to electronegative atom. Ions are then formed. An ionic bond is created between the positively charged and negatively charged ions. Ionic compounds contain repeating patterns of ions called crystal lattices.Learn more about Chemistry
An element or compound that enters into a chemical reaction is called a reagent, while the elements or compounds that result from a chemical reaction are called products. Reagents can be further defined as reactants, catalysts or solvents.Full Answer >
Yttrium barium copper oxide is a chemical compound containing the four elements in its name. It is represented by the general molecular formula YBa2Cu3O7-x, according to American Elements. It is sometimes abbreviated as YBCO, explains Chemistry World. Its superconductive properties are used industrially in relation to magnets.Full Answer >
A substance comprised of molecules that contain unbalanced localized charges (dipoles) is a polar substance. Polar substances tend to interact with other polar substances and rarely react to a significant degree with nonpolar substances.Full Answer >
Ionic compounds are electrically neutral because the charges of the cations and anions that make up the compound cancel each other out. In the case of salt for example, sodium has a charge of positive one, and chloride has a charge of negative one. Together, they neutralize the compound.Full Answer >
