Question

What is atomicity? Write the formulae of two elements which can exhibit atomicity of 2 and 3.​

Answer 1

Explanation:

Atomicity of an element is a measure of the total number of atoms present in a molecule. For example, an oxygen molecule (written as O2) consists of 2 atoms of oxygen (O) and hence an atomicity of 2. Similarly, an ozone molecule (O3) consists of 3 atoms of oxygen and has an atomicity of 3.
