Question

which of the following elements has no electronegativity, and is inert or non-reactive? mark all correct answers a. neon b. argon c. helium d. fluorine

Explanation:

Noble gases (like Neon, Argon, Helium) have full valence electron shells, making them inert (non - reactive) and they don't have electronegativity as they don't tend to gain or lose electrons. Fluorine is a highly reactive halogen with high electronegativity. So Neon, Argon, and Helium are the correct choices.

Answer:

a. Neon, b. Argon, c. Helium
