The Ca²⁺ ion has a 2+ charge, meaning it has lost two electrons. To achieve a stable electron configuration, it would likely form an ionic bond with a nonmetal that can gain two electrons.
Among the options given:
- Neon (Ne) is a noble gas and typically does not form ions.
- Carbon (C) usually forms covalent bonds and does not readily gain two electrons.
- Oxygen (O) can gain two electrons to achieve a stable electron configuration.
- Fluorine (F) can also gain one electron to achieve a stable electron configuration.
The nonmetal that would most likely form an ionic bond with Ca²⁺ in a 1:1 ratio is oxygen (O). Therefore, the correct choice is C) one atom of oxygen.
