Questions and Answers

What is the reason for transition elements exhibiting less electro positivity than the s-block elements?

  • High ionization energy due to large size
  • High ionization energy due to small size (correct)
  • Low ionization energy due to small size
  • Low ionization energy due to large size
  • Why do the d-block elements exhibit an increase in ionization potentials from left to right?

  • Increase in the size of the (n-1) d subshell
  • Decrease in the screening effect of new electrons
  • Decrease in the number of electrons in the (n-1) d subshell
  • Screening effect of new electrons in the (n-1) d subshell (correct)
  • What happens to the second ionization energies of the first transition series with the increase in atomic number?

  • They fluctuate due to stable electronic configuration
  • They remain constant due to stable electronic configuration
  • They increase due to stable electronic configuration (correct)
  • They decrease due to stable electronic configuration
  • What trend is observed for ionization energy across a period?

    Study Notes

    Transition Elements vs. S-Block Elements

    • Transition elements exhibit less electro positivity than s-block elements because the outermost d-subshell in transition elements shields the nuclear charge less effectively, resulting in a lower electro positive character.

    Ionization Potentials in D-Block Elements

    • The d-block elements exhibit an increase in ionization potentials from left to right due to the increase in nuclear charge, which leads to a stronger attraction between the nucleus and the electrons, making it more difficult to remove an electron.

    Second Ionization Energies in the First Transition Series

    • The second ionization energies of the first transition series increase with the increase in atomic number, as the nuclear charge increases, resulting in a stronger attraction between the nucleus and the electrons, making it more difficult to remove a second electron.

    Ionization Energy Across a Period

    • The ionization energy increases across a period due to the increasing nuclear charge and the decreasing atomic radius, resulting in a stronger attraction between the nucleus and the electrons, making it more difficult to remove an electron.
