Slide 11:

The electronic configuration of transition metals determines their properties.
The d-orbitals can hold a maximum of 10 electrons.
This gives the transition metals the ability to exhibit multiple oxidation states.
Examples include Fe^2+ and Fe^3+, which have different electron configurations.

Electronegativity is the tendency of an atom to attract a shared pair of electrons towards itself.
The Lanthanides and Actinides generally have similar electronegativities to their s- and p-block counterparts.
Transition metals have lower electronegativities due to their larger atomic size and less effective nuclear charge.

Reactivity of the f-block and d-block elements depends on their electronic configuration and the stability of oxidation states.
Lanthanides are mostly trivalent, but some elements (e.g., Eu and Yb) can have multiple oxidation states.
Actinides can exhibit a wide range of oxidation states, from +3 to +7 and even higher.
