In explanation, chemical property is a
characteristic of a certain substance came from an outcome due to chemical change
or reaction. In the situation above, more specifically toxicity is involved in

a process of degeneration of metals. Here it works the same. Toxicity is how
much damage did a certain entity do to the object. </span>
