WebElectron affinity (the energy associated with forming an anion) is more favorable (exothermic) when electrons are placed into lower energy orbitals, closer to the nucleus. Therefore, electron affinity becomes increasingly negative as we move left to right across the periodic table and decreases as we move down a group. WebThe Electron Affinity trend, like other trends in the periodic table, reflects the fact that electron affinity follows a predictable trend as one reads the periodic table. In this case, electron affinity increases from top to …
Second electron affinity of an element is: (1) Always
WebIn general, the first ionization energy increases as we go from left to right across a row of the periodic table. The first ionization energy decreases as we go down a column of the periodic table. ... 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 ... WebPredict: Based on your investigations in activities A and B, predict where in the periodic table you will typically find the following: Largest atoms, smallest atoms, highest ionization energy, lowest ionization energy, highest electron affinity, lowest electron affinity. Upper left region Upper right region Far left column Far right column ... picnic cooler bag nz
Electron affinity - Wikipedia
WebSep 14, 2024 · Explanation: Electron affinity generally increases from left to right and from bottom to top. 9. Answer: C.) Oxygen (O) Explanation: Periodic trends indicate that … WebOn the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group. As a result, the most … WebPeriodic Trends in Element Properties Electron affinity (EA): is a measure of the energy change when an electron is added to a gaseous atom to form an anion S (g) ... • Decreases from left to right because electrons are held closer to the nucleus by the increasingly greater effective nuclear charge (Z eff). picnic cooler bag set
