WebSep 20, 2024 · When does an element gain an electron it gives off energy? The electron affinity of an element is the energy given off when a neutral atom in the gas phase gains an extra electron to form a negatively charged ion. A fluorine atom in the gas phase, for example, gives off energy when it gains an electron to form a fluoride ion. WebJul 3, 2014 · Two Fluorine atoms gains one electrons each ( total of two) from one Sr atoms, each Sr atom loses two electrons ( one each) to two chlorine atoms , in this process each Sr atom becomes Sr2+ ion and each fluorine atom after gaining one electron becomes F − ion. so in all we have one Sr2+ ions and two fluoride F − ions. so the formula becomes Sr F 2.
