Final answer:
Neon (B) would have the highest first ionization energy among Hydrogen, Neon, Fluorine, and Chlorine.
Step-by-step explanation:
The atom that would have the highest first ionization energy among Hydrogen, Neon, Fluorine, and Chlorine is Neon (B). Neon (B) would have the highest first ionization energy among Hydrogen, Neon, Fluorine, and Chlorine.
Ionization energy refers to the amount of energy required to remove an electron from an atom in its gaseous state. The noble gases, such as Neon, have a stable electron configuration and therefore require a significant amount of energy to remove an electron, making Neon have the highest first ionization energy.
In contrast, Hydrogen (A) has the lowest first ionization energy among the given options since it only has one electron, which is relatively easier to remove compared to the rest of the elements.
