Answer :
a)All transition elements exhibit similar properties bcz of the identical EC of their peripheral(outer) shell. This happens as each additional electron enters the penultimate 3d shell. This creates an effective shield b/w t's nucleus n the outer 4s shell.
OR
All the d-block elements have the same no of electrons in outermost shell. hence,they show similar chemical properties.
b) ☆Metallic nature
☆Melting n boiling point
☆Atomic radii
☆Ionic radii
☆Atomic vol n Densities
☆Ionization potentials
☆Electronic configuration
