Among the following compounds, the compound(s) which contain both ionic and covalent bonds should be determined. ( NH 4 ) 2 SO 4 , Ca 3 ( PO 4 ) 2 , K 2 O , P 2 O 5 and KCl Concept Introduction: The chemical bond is classified as ionic and covalent bond. Ionic bond: The bond formed between metal and non-metal is known as ionic bond. In ionic bonding, the complete transfer of electrons takes place and it generates two oppositely charge ions (positive charged ion and negative charged ion). In simple words, it is an electrostatic attraction present between opposite charge ions. Covalent bond: The bond in which sharing of electrons takes place between atoms is known as covalent bond. In terms of electronegativity difference, when the electronegativity difference present between two atoms is less than 2.0, then the bond is covalent whereas if the electronegativity difference present between two atoms is equal to 2.0 or greater than 2.0, then the bond is ionic.

Interpretation Introduction

Interpretation:

Among the following compounds, the compound(s) which contain both ionic and covalent bonds should be determined.

( NH4)2SO4, Ca3( PO4)2, K2O, P2O5 and KCl

Concept Introduction:

The chemical bond is classified as ionic and covalent bond.

Ionic bond: The bond formed between metal and non-metal is known as ionic bond. In ionic bonding, the complete transfer of electrons takes place and it generates two oppositely charge ions (positive charged ion and negative charged ion). In simple words, it is an electrostatic attraction present between opposite charge ions.

Covalent bond: The bond in which sharing of electrons takes place between atoms is known as covalent bond.

In terms of electronegativity difference, when the electronegativity difference present between two atoms is less than 2.0, then the bond is covalent whereas if the electronegativity difference present between two atoms is equal to 2.0 or greater than 2.0, then the bond is ionic.
