lead
“Lead” is a chemical element with the atomic number 82 and is a type of heavy metal.
Lead is a conductor of electricity and is often used as a component in solder as it has a low melting point of 327.5C (621.5F).
Lead was also used to make many different colours of paint, but this practice stopped as lead is highly toxic.
It is important to note that lead, as in the apparatus commonly tied to one’s neck, is meant to be tagged as “leash”.
