Which one of the following arrangements represents the correct order of electron gain enthalpy ( with negative sign ) of the given atomic species ?
A.
$$Cl < F < S < O$$
B.
$$O < S < F < Cl$$
C.
$$S < O < Cl < F$$
D.
$$F < Cl < O < S$$
Answer :
$$O < S < F < Cl$$
Solution :
The correct order of electron gain enthalpy or (electron affinity) is
$$O < S < F < Cl$$
( Value of electron affinity in $$eV$$ ) 1.48 2.07 3.45 3.61
