DifficultGiven below are two statements:
Statement-$I$: $C < O < N < F$ is the correct order in terms of first ionization enthalpy values.
Statement-$II$: $S > Se > Te > Po > O$ is the correct order in terms of the magnitude of electron gain enthalpy values.
In the light of the above statements, choose the correct answer from the options given below:
Statement-$I$: $C < O < N < F$ is the correct order in terms of first ionization enthalpy values.
Statement-$II$: $S > Se > Te > Po > O$ is the correct order in terms of the magnitude of electron gain enthalpy values.
