The Most Surprisingly Serendipitous Words Of The Day. Ionic bonds, also known as salt bonds, are a type of chemical bond that is formed after two or more atoms or chemical groups lose or gain electrons and become ions. The American Heritage® Science Dictionary Forum. Ionic bonding results in compounds known as ionic, or electrovalent, compounds, which are best exemplified by the compounds formed between nonmetals and the alkali and alkaline-earth metals. These bonds can form between a pair of … General Biology. Classes. Groups of two or more atoms held together by chemical bonds. Electrons are negatively charged. Physical Science. Covalent bonds. Ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. An ion is defined as an atom or molecule that has gained or lost one or more of its valence electrons, giving it a net positive or negative electrical charge.In other words, there is an imbalance in the number of protons (positively charged particles) and electrons (negatively charged particles) in a chemical species. Bonds created by sharing electrons between atoms. Ion Definition Biology. Why Do “Left” And “Right” Mean Liberal And Conservative? Ionic bonds arise as cationic and anionic components of protein such as cationic and anionic species are found as acidic and basic groups. These bonds can form between a pair of atoms or between molecules and are the type of bond found in salts. Ionic bond is a kind of chemical bond which involves an electrostatic attraction between two oppositely charged ions because of the complete transfer of valence electrons between them. There is a high electrostatic attraction between the cations and anions. This video is unavailable. Published by Houghton Mifflin Harcourt Publishing Company. This is the currently selected item. The sodium atom has a single electron in its outermost shell, while chlorine needs one electron to fill its outer shell.

Ionic bonds typically form when the difference in the electronegativities of the two atoms is great, while covalent bonds form when the electronegativities are similar. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom. The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion (anion). Metallic sodium, for example, has one valence electron in its…. Omissions? In ionic crystalline solids of this kind, the electrostatic forces of attraction between opposite charges and repulsion between similar charges orient the ions in such a manner that every positive ion becomes surrounded by negative ions and vice versa. The attractive force which holds various constituents (atoms, ions, etc) together in different chemical species to maintain a mutual atomic and a definite but specific geometrical shape, is called a chemical bond. A chemical bond in which one atom gives up an electron to another, thereby generating an electrical force that holds the atoms together.
