Questions and Answers

What is the general trend in atomic radius as you move down a group in the periodic table?

  • It increases due to the addition of more energy levels. (correct)
  • It decreases due to the decrease in nuclear charge.
  • It alternates between increase and decrease.
  • It remains the same.

    • What is the primary reason for the decrease in atomic radius as you move across a period in the periodic table?

  • Shielding effect of electrons.
  • Decrease in nuclear charge.
  • Increase in nuclear charge. (correct)
  • Addition of more energy levels.

    • What is the general trend in ionization energy as you move down a group in the periodic table?

  • It increases due to the decrease in atomic size.
  • It remains the same.
