1》 d-Block Elements have high density because they have small size high atomic mass and close packing of particles.
2》 d-Block Elements have high enthalpy of atomisation due to unpaired electrons stronger metallic bonding.
3》 Due to strong metallic bonding d-Block Elements have high melting point
4》 Due to smaller size high effective nuclear charge .
5》 Due to unpaired electron and d-d transition.
