The inorganic Tl(I) compounds are far more stable in a water solution with neutral pH than the Tl(III) compounds. On the other hand, the covalent organic thallium compounds are only stable for Tl (III). Each ionic form has different bioavailability and toxic properties. The Tl(III) cations are much more reactive and toxic than the Tl(I) ones.

The elements that form bonds by donating electrons are called cation. The thallium atom donates three electrons in the last shell to form a thallium ion(Tl 3+). That is, thallium is a cation element.
