Question: Which element has the lowest ionization energy? Ionization Energy. Ionization energy is the amount of energy required to remove an electron from the gaseous form of an element. Electron affinity is the energy change that results from adding an electron to a gaseous atom. For example, when a fluorine atom in the gaseous state gains an electron to form F⁻(g), the associated energy change is -328 kJ/mol. Because this value is negative (energy is released), we say that the electron affinity of fluorine is favorable. Some elements has a low first ionization energy, for others this value is bigger. ...

Because positive charge binds electrons more strongly, the second ionization energy of an element is always higher than the first. Aug 24, 2020 · Asked for: element with lowest first ionization energy. Strategy: Locate the elements in the periodic table.

General trends in the ionization energy of elements in the Periodic Table: ⚛ Ionisation energy decreases down a group. ⚛ Ionisation energy increases across a period from left to right. Aug 13, 2020 · If we plot the first ionization energies vs. atomic number for the main group elements, we would have the following trend: Figure \(\PageIndex{1}\): Ionization energy and atomic number. Moving from left to right across the periodic table, the ionization energy for an atom increases. We can explain this by considering the nuclear charge of the atom. 10. Which atom below has the largest first ionization energy? a) N b) O c) S d) Li e) Cs. 11. Which statement is INCORRECT? a) Electron affinity is the amount of energy needed to attach an electron to a gaseous element. b) Once an electron has been removed from a neutral atom, the second electron is usually easier to remove.
