2. Chemical Bonding
Chemical bonding provides the energy necessary to
hold two different atoms together as part of a chemical
compound.
Strength of the bond depends the molecules or atoms
involved in the process of bond formation.
3. Ionic Bond
It is when an electron leaves one atom and
exothermally enters into orbit around another.
These to oppositely charged ions now attracteach
other.
These bond are generally formed between
Metals and Non-Metals
e.g.
Na(+)+Cl(-)
4. Covalent bond
The mutual sharing off electrons between two
atoms is called Covalent bond.
It is further classified into single, Double, and
Trible covalent bond with respect to mutual sharing of
one, two or three bonds respectively
5. Hydrogen Bond
It is an electrostatic attraction between Hydrogen
atoms bonded to small, Strongly Electronegative
atoms(N, O & F) and the lone pair electrons on the
electronegative atoms
6. Metallic Bond
Bonding of metal atoms to metal atoms
Metals lose valence electrons to become positive
ions.
Positive ions vibrate about a fixed position while
lost elctron free to more around Positive(+)ions
E.g.,
cu2+, Al3+,etc…
