Actinides are all soft and silver in color (but not when exposed to air). They are dense and malleable. Most actinides have the same properties as the d-block.

What two groups are metals are classified under?

Most scientists regard metals in one of three groups Alkali, alkaline earth metals, and transition metals. The transition metals are further divided into lanthanides and actinides groups on the periodic table. One could also consider metals divided by ferrous and non-ferrous. This generally speaks of iron carrying metals and magnetic properties versus non-iron and nonmagnetic.
