Noble gases are named so because they are:
Correct answer: D. All of the above
- A. Less reactive
- B. Zero group elements
- C. Completely filled valence shell
- D. All of the above
Explanation
Noble gases are named for their inert nature, characterized by three significant features:Less reactive: Due to their completely filled valence shells, they have little urge to gain or lose electrons,leading to low reactivity.Zero group elements: They belong to Group 18, also known as the zero group, because their stable electron configuration renders them unreactive with other elements.Completely filled valence shell: This configuration contributes to their low reactivity and inertness.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
