Which family in the periodic table has metals that are usually harder than other metals? Alkali metals
Alkaline earth metals
Lanthanide series
Transition metals

Transition metals

Explanation:

The transition metals are usually harder than other metals such as the alkali metal, lanthanide series metals and the alkaline earthmetals.

The reason for this is because they have a stronger metallic bonding between their atom.

Hardness is a physical property which is attributed to intermolecular forces and the atomic arrangement

The transition metals are found in the d - block on the periodic table.

They have a d-orbirtal which confers extra electrons and higher degree of stability to the atom. The d-orbirtal provides more delocalized electrons for the metallic bonds formed.

fumikage isn't really a bird, and tsuyu does have teeth. tsuyu has a transformation quirk which still allows her to be partially human. otherwise we'd have a large frog running around. fumikage has teeth because again, he isn't a bird. his head was a quirk mixture if i'm correct.
