Answer:

The decrease in size of lanthanide ion due to increase in atomic number is known as lanthanide contraction. Consequences of lanthanide contraction: • Hard to separate the lanthanides • Increase in electronegativity • Increase in ionisation energy • Ability of complex formation decreases.

Answer:

The Lanthanide Contraction is caused by a poor shielding effect of the 4f electrons. Gd because as atomic number increases, the atomic radius decreases. Yb because it has a larger atomic number. These electrons are do not shield good, causing a greater nuclear charge.
