TYPES OF MOLECULES
Molecule
A Molecule is formed by the chemical combination of atoms.
It is the smallest unit of the substance. It shows all the properties of the
substance and can exist independently.
TYPES OF MOLECULES ON THE BASIS OF NUMBER
AND
TYPES OF ATOMS COMBINING.
A few are discussed here:
ON THE BASIS OF NUMBER OF ATOMS
1-Monoatomic Molecule.
A Molecule consisting
of only one atom is called monoatomic molecule.
For Example
The inert gases helium, neon, and argon all
exist independently in atomic form,and they are called monoatomic molecules
2-Diatomic Molecule
If a molecule consists of two atoms ,it is called diatomic
molecule
For example
Hydrogen (H2),Oxygen (O2) Chlorine (Cl2), and
Hydrogen chloride (HCl)
3-Triatomic Molecule.
If a molecule consists of three atoms, it is called
triatomic molecule.
For example
H2O,CO2,O3 etc..
4-Poly Atomic Molecule
If a molecule consists of many
atoms,it is called poly atomic molecule
For example
Methane( CH4),
Sulphuric Acid(H2SO4), and glucose (C6H12O6)
ON THE BASIS OF TYPE OF ATOMS COMBINING
5- Homoatomic Molecule.
A Molecule containing same type of
atoms, it is called homoatomic Molecule.
For example
Hydrogen (H2), Ozone
(O3), Sulphur (S8), phosphorus (P4)
6-Hetroatomic Molecule
When a molecule consists of
different kinds of atoms, it is called hetroatomic molecule
For example
H2O,NH3
