Atomicity : The number of atoms present in a molecule is defined as the atomicity.
Coming to assertion we are given that atomicity of O₃ is 3 . It is true beacuse number of atoms in O₃ molecule is 3 oxygen atoms . So , Assertion is true
Coming to the reason , 1 mole of an element contains 6.023 × 10²³ atoms . The given statement is true. 1 mole of any substance contains 6.023 × 10²³ atoms . But Reason is not the correct explanation of Assertion . Because here the reason is not giving information about atomicity. So , Reason is correct but not the correct explanation of assertion
Hence , Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
