Question

is lanthanoid contraction more than general trend of decrease in atomic radii​

Answer 1

Answer:

The lanthanide contraction is the greater-than-expected decrease in ionic radii of the elements in the lanthanide series from atomic number 57, lanthanum, to 71, lutetium, which results in smaller than otherwise expected ionic radii for the subsequent elements starting with 72, hafnium.

Answer 2

Answer:

Ya, lanthanide contraction is more than general trend of decrease in atomic radii.

Explanation:

The results of the increased attraction of the outer shell electrons across the lanthanide period may be divided into effects on the lanthanide series itself including the decrease in ionic radii, and influences on the following or post-lanthanide elements.
