Lanthanide Contraction Explained in 60 Seconds | Class 12 Chemistry | JEE NEET
Lanthanide contraction refers to the gradual decrease in atomic and ionic radii of lanthanide elements from La to Lu. This happens due to poor shielding effect of 4f electrons, which increases the effective nuclear charge and pulls electrons closer to the nucleus. 📌 Why is it important? Explains similarity between 4d & 5d elements Affects ...
