Understanding Electron Gain Enthalpy
Electron gain enthalpy refers to the energy change when an electron is added to a neutral atom in the gas phase. A more negative value indicates a greater tendency to gain an electron, which is crucial for understanding the reactivity of nonmetals.
Elements Under Consideration
The elements provided are:
- Phosphorus (P) - Atomic number 15
- Sulfur (S) - Atomic number 16
- Chlorine (Cl) - Atomic number 17
- Fluorine (F) - Atomic number 9
- Bromine (Br) - Atomic number 35
Analysis of Electron Gain Enthalpy
- Chlorine (Cl): Chlorine has the most negative electron gain enthalpy among the listed elements. This is due to its high electronegativity and the effective nuclear charge experienced by the added electron. Chlorine readily accepts an electron to achieve a stable noble gas configuration (like Argon).
- Fluorine (F): Although fluorine is highly electronegative, its small size leads to significant electron-electron repulsion when an additional electron is added, resulting in a less negative electron gain enthalpy compared to chlorine.
- Bromine (Br): Bromine's larger atomic size results in a less favorable electron gain enthalpy than chlorine.
- Sulfur (S) and Phosphorus (P): Both have less negative electron gain enthalpies than chlorine due to their larger atomic radii and lower electronegativity than chlorine.
Conclusion
Therefore, the element with the most negative electron gain enthalpy in the given list is Chlorine (Cl), with an atomic number of 17. This characteristic makes chlorine highly reactive, particularly in forming ionic bonds.
