And...."14 actinides..."14 actinides..., thorium, Z=90Z=90, to lawrencium, Z=103Z=103...

"f-element"f-element chemists often include the Group 3 metals in their research, i.e. scandium, ytrrium, lanthanum, and actinium, because these large, Lewis-acidic metals, have very similar (and stubborn) chemistry....so that makes 32 such metals...
