Question

Lanthanides contraction cause

• A. small decrease in standard electrode potential value of lanthanides
• B. small decrease in basic strength of oxides of lanthanides
• C. small variation in chemical properties of lanthanides
• D. small increase in electronegativities of lanthanides

Answer 1

Answer: (D)

Electronegativity increases as we move from left to right due to lanthanide contraction
