It is known to be a potential energy change of an atom. We must know that the more negative the electron affinity the more favorable the process of electron addition is. Complete step-by-step answer:We must know that not all elements form stable negative ions in which case the electron affinity is zero or even positive. When we look at the periodic trends, the electron affinities are not easy to measure. As we move from left to right across a period, the electron affinity increases. This is known to occur due to an increase in nuclear attraction.As we go down the group, we can see that the electron affinity decreases. This occurs as the electron is being added further away from the nucleus more and more causing the bond to weaken and thus losing an electron is easier. Atomic size decreases as we move from left to right across a period due to the increase in nuclear forces and thus we know that the electron gain enthalpy increases. Whereas while moving down a group we can see that the atomic size constantly increases thereby causing a decrease in the value of electron gain enthalpy.Factors which affect electron affinity are –1.Atomic size2.Effective nuclear charge 3.Screening effectNote: It is important to note that first electron affinity is always exothermic. This means that negative the second electron affinity of the same element will be positive or endothermic. This is so because the second electron has to be forced to enter the mono negative ion. The electron affinity cannot be determined directly but is obtained indirectly from the Born-Haber cycle.Recently Updated PagesMaster Class 11 Economics: Engaging Questions & Answers for SuccessMaster Class 11 Accountancy: Engaging Questions & Answers for SuccessMaster Class 11 English: Engaging Questions & Answers for SuccessMaster Class 11 Social Science: Engaging Questions & Answers for SuccessMaster Class 11 Biology: Engaging Questions & Answers for SuccessMaster Class 11 Physics: Engaging Questions & Answers for SuccessMaster Class 11 Economics: Engaging Questions & Answers for SuccessMaster Class 11 Accountancy: Engaging Questions & Answers for SuccessMaster Class 11 English: Engaging Questions & Answers for SuccessMaster Class 11 Social Science: Engaging Questions & Answers for SuccessMaster Class 11 Biology: Engaging Questions & Answers for SuccessMaster Class 11 Physics: Engaging Questions & Answers for Success12Trending doubts1 ton equals to A 100 kg B 1000 kg C 10 kg D 10000 class 11 physics CBSEAt which age domestication of animals started A Neolithic class 11 social science CBSEDifference Between Prokaryotic Cells and Eukaryotic CellsOne Metric ton is equal to kg A 10000 B 1000 C 100 class 11 physics CBSE1 Quintal is equal to a 110 kg b 10 kg c 100kg d 1000 class 11 physics CBSEDraw a diagram of nephron and explain its structur class 11 biology CBSE1 ton equals to A 100 kg B 1000 kg C 10 kg D 10000 class 11 physics CBSEAt which age domestication of animals started A Neolithic class 11 social science CBSEDifference Between Prokaryotic Cells and Eukaryotic CellsOne Metric ton is equal to kg A 10000 B 1000 C 100 class 11 physics CBSE1 Quintal is equal to a 110 kg b 10 kg c 100kg d 1000 class 11 physics CBSEDraw a diagram of nephron and explain its structur class 11 biology CBSE12NEET Repeater 2023 - Aakrosh 1 Year CourseStudy materialNCERTReference book solutionsCompetitive ExamsCBSEICSE State boardsFree Study MaterialImportant SubjectsRevision Notes JEE MAINJEE ADVANCED NEET OFFLINE CENTRES © 2025.Vedantu.com.

Definition: The first electron affinity is the energy change accompanying the addition of an electron to a neutral atom in its gaseous state to form a negative ion., Definition: Electron affinity measures the energy change when an electron is added to a neutral atom in the gas phase, forming an anion (a negatively charged ion). This process can either release energy or require energy, depending on the element involved., Hint: The energy release in the process of adding an electron to a neutral gaseous isolated atom and forming a negatively charged ion is called electron affinity., electron affinity is quantitative measurement of the energy change that occurs when an electron is added to a neutral gas atom. The larger the atom the lower the ionization energy. Easier to remove because the nucleus protons have less of a hold. What methods can you use to figure out which specie has the higher ionization energy? 1., Electron affinity is the energy change that occurs when an electron is added to a gaseous atom. The more negative (exothermic) the value, the greater the affinity., .
