Question

What is the atomicity of CH4

Answer 1

Answer:

1 Carbon atom + 4 hydrogen atom = 5 atoms. =) atomicity of CH4 = 5. 4.5.

Answer 2

Atomicity

Explanation:

Atomicity is  defined as the total number of atoms constitute a molecule.

Division of molecules on the basis of atomicity

• Monoatomic - It isconsistof 1 atom e.g. He, Ne, Ar

• Diatomic- It is consist of 2 atoms e.g. H₂ , N₂ , O₂

• Triatomic- It is consist  of 3 atoms e.g. O₃

• Polyatomic- It is consist  of 3 or more atoms e.g. P₄ , S₈

Example of CH₄

Molecular mass= (1 × Atomic mass of carbon) + (4 × Atomic mass of hydrogen)

                            = [1 (12.011 u) + 4 (1.008 u)]

                             = 12.011 u + 4.032 u

                             = 16.043 u
