The change in energy for which of the following processes corresponds to the first ionization energy of beryllium? A) Be(g)→ Be⁺(g)+ e^- B) Be(s)→ Be⁺(s)+ e^- C) Be(s)→ Be⁺(g)+ e^- D) Be(g)→ Be²⁺(g)+ 2e^- E) Be(s)+ e^- → Be^-(s)

Question

Quizplus · Accepted Answer

The first ionization energy refers to the energy required to remove the outermost electron from a gaseous atom, making choice A correct as it shows a beryllium atom in the gas phase (Be(g)) losing an electron to form a positively charged ion (Be+).
