Lead is defined as what type of substance?

Explanation:
Lead is a toxic heavy metal. In regulatory terms, it is classified by its hazard as a metal with significant health risks, especially neurotoxic effects in humans. It is not a noble gas—the noble gases are inert, nonmetal gases like helium or neon. It isn’t a non-toxic metal, since lead’s toxicity is well established. It isn’t a pesticide; while some lead-containing compounds have been used in pesticides historically, lead itself is not considered a pesticide.
