Answer 2

$\fbox\blue{ What are Molecules? }$

• Molecules are the smallest particles of any substance.

• A molecule is formed when two aur more atoms of the same different types of elements combine in a fixed ratio.

• It is responsible for all physical and chemical properties of that particular substance.

• Molecules are of three types : Monoatomic, diatomic and polyatomic.

• Atoms in a molecules are held together with two types of bonds : ionic bond and covalent bond.

• If we break molecule then properties of that substance are lost.

Additional Information –

• Monoatomic –It is Composed of particle with single atom. there are no chemical bonds between particles. Monu atomic species except noble gases are not that stable.

• Diatomic – It is composed of molecules with two atoms. there are ionic and covalent bond between two atoms. Diatomic compounds are stable.

• Polyatomic – It is composed of several ions per atom. there are covalent and co-ordinate bonds. formed by bonding several atoms together.
