Inner transiton metals and inner transiton elements... So both a and c
Generally speaking, the lanthanides are naturally occurring and stable, although relatively uncommon. The actinides are naturally occurring through uranium; after that, they're synthetic, and all are unstable (radioactive.)
Elements between 57 and 70 belongs to the f group. Elements from La - Lu belongs to this group. These are called Lanthanides.These elements are Lanthanides. They are placed separately. They have different chemical properties.
Some lanthanides are radioactive, such as promethium. However, most lanthanides found in nature are stable.
Actinides and lanthanides lose electrons and form cations.
The densities of the lanthanides generally have less variability compared to the densities of the actinides. This is because the lanthanides are more similar in size and electronic structure, leading to more consistent densities. In contrast, the actinides exhibit larger variations in density due to differences in atomic structure and electron configurations.

Wht is the difference between Lanthanides and Actinides?
are radioactive and the actinides are not

between Barium and Hafnium
Actinides comprise of atomic number 90-103. They are placed at bottom of periodic table.
Electrons are removed first from the 5d orbital than the 4f orbital in lanthanides because the 5d orbital has higher energy than the 4f orbital. In lanthanides, the energy difference between the 4f and 5d orbitals is small, making it more energetically favorable to remove electrons from the 5d orbital first before the 4f orbital.
describe the complex formation by lanthanides?
Some lanthanides are radioactive, such as promethium. However, most lanthanides found in nature are stable.
Actinides and lanthanides lose electrons and form cations.
The elements with atomic numbers from 58 to 71 are called the lanthanides. They are a group of metallic elements that have similar chemical properties due to their electron configurations. The lanthanides are commonly used in various applications such as in the production of electronic devices and catalysts.
