Understanding the Answer
Let's break down why this is correct
Answer
The element with the highest first ionization potential is helium. Helium’s single electron shell (1s²) is completely filled, making it a very stable, noble‑gas configuration. Because its two electrons are held tightly by a strong nuclear attraction and the electron cloud is very small, it takes a lot of energy to remove one of them. This is why helium’s first ionization energy (about 24. 6 eV) is higher than that of any other element.
Detailed Explanation
Neon is a noble gas, meaning its outer electron shell is full. Other options are incorrect because Sodium is an alkali metal; Chlorine is a halogen that likes to gain an electron.
