Covalent Bonds
Covalent chemical bonds involve the sharing of a pair of valence electrons by two atoms, in contrast to the transfer of electrons in ionic bonds. Such bonds lead to stable molecules if they share electrons in such a way as to create a noble gas configuration for each atom.
Hydrogen gas forms the simplest covalent bond in the diatomic hydrogen molecule. The halogens such as chlorine also exist as diatomic gases by forming covalent bonds. The nitrogen and oxygen which makes up the bulk of the atmosphere also exhibits covalent bonding in forming diatomic molecules.
Covalent bonding can be visualized with the aid of Lewis diagrams
Ionic Bonds
In chemical bonds, atoms can either transfer or share their valence electrons. In the extreme case where one or more atoms lose electrons and other atoms gain them in order to produce a noble gas electron configuration, the bond is called an ionic bond.
Typical of ionic bonds are those in the alkali halides such as sodium chloride, NaCl.
Ionic bonding can be visualized with the aid of Lewis diagrams.
Metallic Bonds
The properties of metals suggest that their atoms possess strong bonds, yet the ease of conduction of heat and electricity suggest that electrons can move freely in all directions in a metal. The general observations give rise to a picture of "positive ions in a sea of electrons" to describe metallic bonding.

ionic bonds-when two opposite ions came in contact with each other then due to huge attraction they stuck with each other and leads to formation of ionic bonds.
these bonds have high strength not easily breakable.
eg:-NaCl,MgCl2 etc
Covalent bonds-covalent bonds form due to mutual sharing of electron among two atoms to gain stability.
e.g. O2,CO2 etc
metallic bonds-Metallic bonding is a type of chemical bond that arises from the electrostatic attractive force between conduction electrons and positively charged metal ions.
the difference between ionic and metallic bond is very little,in ionic bond we use anion and cation while in metallic bond metal ion and electron.
thanx
