Question

Which element gains an electron in the most exothermic process?

Answer 1

The element that gains an electron in the most exothermic process is typically fluorine (F). Fluorine has a high electron affinity, meaning it releases a significant amount of energy when it gains an electron to form a fluoride ion (F⁻). This high energy release is due to fluorine's strong electronegativity and its desire to achieve a stable electron configuration similar to that of noble gases. As a result, the process of fluorine gaining an electron is one of the most energetically favorable, or exothermic, among the elements.
