Ionic Bond Definition

A bond which links atoms, molecules together is known as chemical bond. There exists 3 types of chemical bond and they are Ionic bond, covalent bond and hydrogen bonds and these are bound by electrostatic attraction.

In ionic bond there is shift of electron from the donor to the acceptor. The shift happens usually from a metal which is the donor and will be a cation after donating (positive charge) to the non-metal which is the acceptor and will be anion after receival of electron.

To the name of the ion or molecule “ide” is attached at the end which obtains an electron. Example is conversion of chlorine to chloride and sulfur to sulfide.

What is Ionic Bond?

There could be two types of forces seen between the atoms and ion. When two oppositely charged ions attract each other it is called as electrostatic attraction, whereas ions of same charge will oppose each other, thus electrostatic repulsion. There is electrostatic attraction in the ionic bond, where anions get drawn towards the cation which depends on the gap between the two atoms, their size and the forces on them.

Until the octet configuration is accomplished, electrons will get shift from the donor to the receiver, resulting in zero charge on the donor existing in the form of crystals.

Ionic Bond Examples

A bond which links atoms, molecules together is known as chemical bond. A chemical compound consist of various forms of atom, resulting from a chemical bond. Chemical element are those which contain one type of atom. The bond which clutches the chemical compound is called as ionic compound.

Sodium chloride is the ionic compound in which sodium and chloride are bound by ionic bond.

The overall charge is zero as one ion is positive and the other is negative, thus balancing and resulting in zero charge. Those compounds are said to be acidic which has hydrogen ions and those are basic which has hydroxide ion, together forming a salt.

Ionic Bond vs Covalent Bond

Shift of electrons take place between the donor electron to receiver in ionic bond, whereas in covalent bond there is electron sharing taking place in between the two atoms. After the ionic bond, an ionic compound is formed.

Electronegativity is same in covalent bond, whereas in ionic bond the one that receives the electron is more electronegative. When the cations and anions come together in an electrostatic attraction, they form a salt, whereas no salt formation is seen in covalent bond.

Covalent compound are in liquid or gaseous state at room temperature, whereas ionic compound are in the crystalline form. Covalent compound can have single, double and triple bond and are less polar. Ionic bond has high polarity.

Ionic Bond vs Hydrogen Bond

Shift of electrons take place between the donor electron to receiver in ionic bond, whereas in hydrogen bond, between the two atom a bridge is formed.

Example of ionic bond is sodium chloride and of hydrogen bond is water molecule. For the formation of hydrogen bond, a minute positive hydrogen atom with covalent bond that is polar interacts with polar negative atom with covalent bond results in a hydrogen bond.

Although hydrogen bond is the weakest, the secondary and tertiary protein structures are formed by them.
