What are the characteristics of Ionic compounds ? An ionic bond is a bond between ions with opposite charges. Cations (positively charged ions) cannot exist without anions (negatively charged ions). An electron released by an atom to from a cation must be accepted by another atom to form an anion. Cations and anions are formed in many chemical reactions by the transfer of one or more electrons from one element to another. Ionic bonds are formed by a strong attraction between positive and negative ions. Characteristics of Ionic compounds. Some important characteristics of ionic compounds are as follows. 1. Ionic compounds are hard and rigid due to strong forces of attraction between the oppositely charged ions.

- The atoms form positive and negative ions which attract to each other. Ionic compounds are composed of large numbers of positive ions (cations) and negative ions (anions) so that the amount of positive charge equals the negative charge. In covalent bonds the electrons are shared between two bonded atoms.

- Properties of ionic compounds. 1  High melting and boiling points - Ionic bonds are very strong - a lot of energy is needed to break them. So ionic compounds have high melting and boiling points. 2  Conductive when liquid - Ions are charged particles, but ionic compounds can only conduct electricity if their ions are free to move.

Ionic bonding Thus, the term ionic bonding is given when the ionic character is greater than the covalent character—that is, a bond in which a large electronegativity difference exists between the two atoms, causing the bonding to be more polar (ionic) than in covalent bonding where electrons are shared more equally.

Properties of ionic, covalent, and metallic compounds Here is a short list of the main properties of covalent compounds: Most covalent compounds have relatively low melting points and boiling points. Covalent compounds usually have lower enthalpies of fusion and vaporization than ionic compounds. Covalent compounds tend to be more flammable than ionic compounds. When dissolved in water, they don't conduct electricity. Maybe you'll be interested in comparison of properties of ionic and covalent compound so here is a link where you can learn it.

Which pairs of elements are likely to form ionic compounds? ionic compounds are formed between elements which have a very high difference in electronegativity. Electronegativity is the property of an element to pull electrons. When the difference electronegativity is high (i forgot the specific number) the more electronegative atom completely takes away an electron from the less electronegative atom.

Chemistry Chapter 6 The interaction of so many positive ions with negative ions gives ionic compounds considerable stability in the crystal lattice verses the individual elements. Because stable = lower in potential energy, this extra energy is given off as heat during the formation of ionic compounds.
