The effect of lanthanoid contraction in the lanthanoid series of elements by and large means :

Multiple Choice Options

  • A increase in atomic radii and decrease in ionic radii
  • B increase in both atomic and ionic radii
  • C decrease in both atomic and ionic radii
  • D decrease in atomic radii and increase in ionic radii

Step-by-Step Verified Solution

Due to Lanthanoid contraction both atomic radii and ionic radii decreases gradually in the lanthanoid series.
