Explain the various reasons why atoms and molecules form chemical bonds and explain the differences between different types of chemical bonds. Solution Answer : A chemical bond is an attraction between atoms. This attraction may be seen as the result of different behaviors of the outermost or valence electrons of atoms. A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds; or through the sharing of electrons as in covalent bonds. Differences between different types of chemical bonds : .

1. Explain the various reasons why atoms and molecules form chemical bonds and explain the
differences between different types of chemical bonds.
Solution
Answer :
A chemical bond is an attraction between atoms. This attraction may be seen as the result of
different behaviors of the outermost or valence electrons of atoms. A chemical bond is a lasting
attraction between atoms, ions or molecules that enables the formation of chemical compounds.
The bond may result from the electrostatic force of attraction between oppositely charged ions as
in ionic bonds; or through the sharing of electrons as in covalent bonds.
Differences between different types of chemical bonds :
Covalent Ionic Metallic van der waals forces
A covalent bond is
a chemical bond
that involves the
sharing of electron
pairs between
atoms.
Ionic bonding is a type
of chemical bonding that
involves the electrostatic
attraction between
oppositely charged ions,
and is the primary
interaction occurring in
ionic compounds.
Metallic bonding is a type
of chemical bonding that
arises from the
electrostatic attractive
force between conduction
electrons (in the form of an
electron cloud of
delocalized electrons) and
positively charged metal
ions.
Molecules can attract
each other at moderate
distances and repel
each other at close
range.The attractive
forces are collectively
called van der waals
forces.
They are
responsible for
intramolecular
bonding (in-
between
molecules)
They are also
responsible for
intramolecular bonding
(in-between molecules).
They are responsible for
intramolecular bonding
(in-between molecules)
It is responsible for
Intermolecular bonding
(within different
molecules).
These bonds are
vrery strong.
These are also very
strong.
Metallic bond form strong
bonds.
They form weaker
bond.
