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.
True. The lanthanide and actinide series make up the inner transition metals. The lanthanide series includes elements with atomic numbers 57-71 (lanthanides), while the actinide series includes elements with atomic numbers 89-103 (actinides).
The lanthanide and actinide series. Trait of lanthanide: Lanthanum, element 57. Trait of actinide: actinium, element 89.
The lanthanide and actinide series. Trait of lanthanide: Lanthanum, element 57. Trait of actinide: actinium, element 89.
Neither. Magnesium is an alkaline earth metal (group II).
The Lanthanide Series consists of metals. They are known for their high reactivity and ability to form colorful compounds due to their unique electron configurations.

the two groups of metals is the Lanthanide series and the Actinide series.

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.
No uranium is an actinide and is very hard especially depleted uranium
The chemical element with atomic number 57 is Lanthanum (La). It is a Lanthanide, as it is what the rest of the Lanthanides are based on. It has 57 electrons in 6 shells. It is naturally occuring and non-radioactive.
The 4 corners of the block are Sc, Zn, Cn and the icon for the actinide series, to the left of Rf. This is also known as the transition metals
Thorium (Th) is an inner transition metal with 90 electrons. It is a radioactive element that belongs to the actinide series of the periodic table.
