lanthanides and actinides are fairly reactive, but not as much as say, the alkali metals in group 1
The Transition Metals, the Lanthanides and Actinoids.
No, the alkali metals are pretty soft and the metals cesium, gallium, and mercury have very low melting points.
Actinides transition metals lanthanides
Hard
Spoons are not soft, but they are smooth. They are made out of hard metals like aluminum, steel and other metals.
No. Some metals are hard, but some are soft.

Some metals, such as sodium and potassium, are rather soft, while others, such as diamond, are very hard and can easily scratch other substances.
