Vedclass · Answer

(B) Transition elements are characterized by the presence of partially filled $d$-orbitals in their atoms or ions.Due to the small energy difference between $(n-1)d$ and $ns$ orbitals,electrons from both can participate in bonding.This allows transition elements to exhibit variable oxidation states.They generally have high melting points due to strong metallic bonding and are less reactive than $s$-block elements.
