These are bad conductors of heat and electricity.

Vedclass · Answer

(A) $1$. These are bad conductors of heat and electricity: This statement is incorrect. Lanthanoids are metallic in nature and are generally good conductors of heat and electricity,similar to other metals.$2$. These are soft metals: This is true. Lanthanoids are relatively soft metals,and their hardness increases with increasing atomic number.$3$. Coordination number is usually greater than six: This is true. Due to their large ionic radii,lanthanoids often exhibit high coordination numbers,typically ranging from $8$ to $12$ in their complexes.$4$. These are strongly paramagnetic: This is true. Lanthanoids possess unpaired $f$-electrons,which result in paramagnetic behavior. Many lanthanoid ions exhibit strong paramagnetism.

Which of the following properties of lanthanoids is $NOT$ true?
