The element expected to form the largest ion to achieve the nearest noble gas configuration is:
Options
N
Na
O
F
Correct Answer
Na
Explanation
Na⁺ forms by losing one electron to achieve the Ne configuration, while N³⁻, O²⁻, and F⁻ form by gaining electrons. N³⁻ has the largest ionic radius due to highest negative charge and maximum electron-electron repulsion.
