▼

Which of the following is a typical metallic property NOT explicitly mentioned for transition elements in the provided text?

▼

Which element is listed as adopting a hexagonal close-packed (hcp) structure in the 3d series according to the table?

▼

What characteristic distinguishes the bonding in transition metals from that in alkali metals, contributing to properties like high melting points?

Transition metals have ionic bonding.
Transition metals have covalent bonding.
Alkali metals involve more electrons in bonding.
Greater number of electrons involved in metallic bonding, including d electrons.

▼

Why are transition metals (excluding Zn, Cd, Hg) generally described as 'hard'?

Due to their large atomic radii.
Due to the presence of unpaired f electrons.
Due to the weak interatomic forces in their structures.
Due to the strong interatomic forces resulting from extensive metallic bonding involving d electrons.
