Question

Na Explanation: An element loses an electron more easily if it has a lower ionisation enthalpy, which is characteristic of alkali metals like sodium. Sodium has only one valence electron in its outermost shell (2, 8, 1) and is located furthest to the left in its period, making it the most metallic and electropositive among the choices provided, thus requiring the least energy to lose an electron.
