Question

what are charecterstics of lanthanites and actonites !!​

Answer 1

Explanation:

Properties. Like most metals, the lanthanides have a bright silvery appearance. Five of the elements (lanthanum, cerium, praseodymium, neodymium, and europium) are very reactive. When exposed to air, they react with oxygen to form an oxide coating that tarnishes the surface.

General Properties and Reactions of The Actinides. The Actinide series contains elements with atomic numbers 89 to 103 and is the third group in the periodic table. The series is the row below the Lanthanide series, which is located underneath the main body of the periodic table

Answer 2

The lanthanide and actinide series make up the inner transition metals.

1. The lanthanide series includes elements 58 to 71, which fill their 4f sublevel progressively.

• The actinides are elements 89 to 103 and fill their 5f sublevel progressively.
