Question

Give two similarities in the properties of

Sc

and

Zn

.

Accepted Answer

The two similarities in the properties of $Sc$ and $Zn$ are:

$Sc$ and $Zn$ both form colourless compounds. Scandium typically forms colourless compounds. For example, scandium oxide is white and colourless. Zinc compounds, such as zinc oxide, are also colourless. Zinc itself is a metallic element and is not commonly found in coloured compounds.

$Sc$ and $Zn$ both form diamagnetic. When a substance contains paired electrons, the electrons in each pair have opposite spins. Therefore, the magnetic field created by one electron is cancelled by that created by the other electron because the magnetic fields created by the electrons belonging to a pair are equal and opposite. Thus, the net magnetic field of the substance is zero and the substance has no net magnetic moment. Such a substance shows diamagnetism and is repelled by the applied magnetic field.
