(a) Lanthanides (b) Actinides​

Answer 1

$\huge \purple A \purple N \purple s \purple W \purple e \purple \R :-$

• As a consequence, the chemistry of the elements is largely determined by their size, which decreases gradually with increasing atomic number. This phenomenon is known as the lanthanide contraction. All the lanthanide elements exhibit the oxidation state +3. Actinides are typical metals.
