What is the reason for the increased shielding as you move down a group in the periodic table?

Options

  1. AThe outermost electrons are closer to the nucleus.
  2. BThe outermost electrons experience greater attraction to the nucleus.
  3. CThe inner core of electrons is more filled.
  4. DThe number of electrons in the outermost shell increases.

Correct answer

C. The inner core of electrons is more filled.
