classify molecules on the basis of of type of atom present in by giving suitable examples
Answers
Answer:
Monoatomic molecules , Diatomic molecules , Triatomic molecules , Tetraatomic molecules , Polyatomic molecules
Explanation:
The number of atoms contained in a molecule of a substance (element or compound) is called its atomicity.
Based upon atomicity we can classify molecules as follows.
1. Monoatomic molecules: Noble gases like helium, neon, argon, etc., exist in atomic forms, i.e., they are monoatomic.
For example, helium, neon and argon exist as He, Ne and Ar respectively.
2. Diatomic molecules: These molecules consist of two atoms.
For example, hydrogen (H2) Oxygen (O2), Nitrogen (N2) chlorine (Cl2), Carbon monoxide (CO), hydrogen chloride (HCl) and sodium chloride (NaCl).
3. Triatomic molecules : These molecules consist of three atoms. For example, ozone (O3) is a triatomic molecule. Similarly, carbon dioxide (CO2), nitrogen dioxide (NO2) and hydrogen sulphide (H2S) are examples of triatomic molecules.
4. Tetraatomic molecules : These molecules consist of four atoms.
For example, P4 is a tetraatomic molecule of phosphorus.
5. Polyatomic molecules : Any molecule containing more than four atoms is called a polyatomic molecule.
For example, sulphur (S8) methane (CH4), nitric acid (HNO3), sulphuric acid (H2SO4), ethanol (C2H2OH).
Answer:
Atoms are defined as “the basic building blocks of matter”. It is the smallest constituent unit of matter that posses the properties of the chemical element. ... Molecules consist of one or more atoms bound together by covalent (chemical) bonds.
