Gradual addition of electronic shell in the noble gases causes a decrease in their?
- A. Ionization energy
- B. Atomic radius
- C. Boiling point
- D. Density
Step-by-step solution
As we move down the noble gas group, an additional electron shell is added, increasing atomic radius and shielding effect. This reduces the electrostatic attraction between the nucleus and the outermost electron, making it easier to remove, thus decreasing ionization energy.
