Yes,zinc has only one oxidation state,its metallic ions are
not coloured and is not used as catalyst.Therefore the characteristic it share with other transition metals is yhe formation of complex ions.
Let's break down each option:
* A. have variable oxidation states: This means a metal can have different "charges" in chemical reactions. While many transition metals do this, zinc usually only has one oxidation state (+2), so this isn't a common characteristic.
* B. form complex ions: This means they can create structures where the metal atom is surrounded by other molecules or ions. Both zinc and other transition metals do this. This is a very important property.
* C. act as a catalyst: This means they can speed up chemical reactions. Many transition metals are good catalysts, but zinc isn't as commonly used for this.
* D. form colored ions: Many transition metals form brightly colored solutions, but zinc ions are usually colorless.
Therefore, the best answer is B. form complex ions.
