Question

what is lanthanide contraction? what are it consequences?​

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. the effect, result, or outcome of something occurring earlier: The accident was the consequence of reckless driving. an act or instance of following something as an effect, result, or outcome. the conclusion reached by a line of reasoning; inference. importance or significance: a matter of no consequence.
