Answer: Toxicity is an example of chemical property.
Explanation:
A physical property is the property which can be observed or recognized without any change in the chemical composition of the substance. For example color, size, density, volume etc.
Where as a chemical property is the property which can only be observed by changing the chemical composition of a substance. For example, the different oxidation states of an atom, reactivity, inflammability etc.
Thus, it is concluded that toxicity is an example of chemical property.
