An ionic compound is a giant structure of ions. The ions have a regular, repeating arrangement called an ionic lattice. The lattice is formed because the ions attract each other and form a regular pattern with oppositely charged ions next to each other. Remember that the lattice arrangement is giant - for example, a single grain of salt may contain 1. The lattice arrangement continues in three dimensions.
Ionic bond , also called electrovalent bond , type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound.

An ionic compound forms when the electrons that bind two or more atoms together can lower their energy by spending more time around the more electronegative atoms than the electropositive ones, thereby causing partial negative and positive charges to develop on the atoms. Atoms bind their electrons to the nucleus with different strengths, depending on subtle differences in the structure and occupation of the atomic orbitals. This is often measured as ionization energy, or the energy required to strip one electron away completely to form a positive ion. Likewise, atoms have different electronegativities. This is an indirect measure of the ability of an atom to bind an extra electron to form a negative ion. When an atom with a low ionization energy typically a metal, like Li forms a chemical bond with a highly electronegative atom typically a main group atom on the right side of the periodic table , like F , then the bonding electrons will tend to spend more time around the electronegative atom, thereby lowering their energy and forming a stronger bond than if the electrons were equally shared by the two atoms.

Ionic bonds are a class of chemical bonds that result from the exchange of one or more valence electrons from one atom, typically a metal, to another, typically a nonmetal. This electron exchange results in an electrostatic attraction between the two atoms called an ionic bond. An atom that loses one or more valence electrons to become a positively charged ion is known as a cation, while an atom that gains electrons and becomes negatively charged is known as an anion. This exchange of valence electrons allows ions to achieve electron configurations that mimic those of the noble gases, satisfying the octet rule. The octet rule states that an atom is most stable when there are eight electrons in its valence shell. Atoms with less than eight electrons tend to satisfy the duet rule, having two electrons in their valence shell. By satisfying the duet rule or the octet rule, ions are more stable.

How do atoms of elements form compounds? The Octet Rule is the basis for the predictions about the charges on ions. Ionic compounds are formed as the result of the formation of positive and negative ions. Electrons are actually transferred from one atom to another to form rare gas electron structures for each ion. The atom which forms a positive ion loses electrons to the atom which gains electrons to form a negative ion. A compound is not stable unless the number of electrons which are lost and gained are equal. Example: Determine the formula of a compound formed by the reaction of sodium and fluoride.
Oxygen, however, does not form ionic compounds with nitrogen (electronegativity = ) because their electronegativities are so similar. Because metals and.
