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.
