1. About 10 % of the lanthanide contraction has been attributed to relativistic effects. 2. Without the lanthanide contraction , a chemical separation of lanthanides would be extremely difficult. 3. This behavior is known as the lanthanide contraction . 4. This leads to " lanthanide contraction ". 5. The elements following the lanthanides in the periodic table are influenced by the lanthanide contraction . 6. Titanium is considerably different from the other two owing to the effects of the lanthanide contraction . 7. The lanthanide contraction is a partial explanation; however, it does not entirely account for this anomaly. 8. Due to lanthanide contraction , yttrium, which is trivalent, is of similar ionic size as dysprosium and its lanthanide neighbors. 9. *( Talk ) 14 : 52, 3 July 2012 ( UTC ) Lanthanide contraction explained Jump to : navigation, search 10. This effect has been termed d-block contraction and is similar to the f-block contraction normally termed the lanthanide contraction .
