What are actinides and lanthanides?
Lanthanides and actinides are elements with unfilled f orbitals. Lanthanides are all metals with reactivity similar to group 2 elements. Actinides are all radioactive elements. Lanthanides are used in optical devices (night vision goggles), petroleum refining, and alloys.
How does plutonium look like?
Physical properties. Plutonium, like most metals, has a bright silvery appearance at first, much like nickel, but it oxidizes very quickly to a dull gray, although yellow and olive green are also reported. At room temperature plutonium is in its α (alpha) form.
Is terbium an actinide?
The valence electrons of the terbium element enter into 4f-orbital so the terbium is not an actinide. It is a lanthanide.
