Atomic No Of Carbon



Atomicity is defined as the total number of atoms present in a molecule. For example, each molecule of oxygen (O2) is composed of two oxygen atoms. So atomicity of oxygen is 2.[1]In older contexts, the term atomicity is sometimes used in the same sense as valency.

What is a carbon atom

On the basis of atomicity, molecules can be classified as:

  • Monatomic – composed of 1 atom e.g. He, Ne, Ar (all noble gases are monatomic)
  • Diatomic – composed of 2 atoms e.g. H2 , N2 , O2
  • Triatomic – composed of 3 atoms e.g. O3
  • Polyatomic – composed of 3 or more atoms e.g. P4 , S8

Each atom of carbon has 6 protons and electrons. The element naturally exists as a mix of three.

Atomic No Of Carbon

All metals and some other elements, such as carbon, do not have a simple structure but consist of a very large and indefinite number of atoms bonded together. Their atomicity cannot be determined and is usually considered as 1.

Atomicity may vary in different allotropes of the same element.
