Answer:
The electron affinity (∆EgH) represents the energy change when an atom gains an electron to form a negatively charged ion (anion). A more negative ∆EgH indicates a more favorable or easier electron gain.
In this case, we have the following ∆EgH values:
- Element A: ∆EgH = -10 eV
- Element B: ∆EgH = -20 eV
- Element C: ∆EgH = -30 eV
- Element D: ∆EgH = -40 eV
The element with the most negative ∆EgH value, which is Element D with ∆EgH = -40 eV, has gained an electron most easily. So, Element D is the one that may have gained an electron most easily among the given elements.
