One can identify lead metal by its bluish-gray color, softness, and density. Lead is also malleable and has a low melting point. Additionally, it can leave a gray streak when rubbed on a surface.
One way to determine if a metal is lead is to conduct a simple density test. Lead is a dense metal, so if you measure the density of the metal and it matches the known density of lead, then it is likely to be lead. Another method is to perform a chemical test using a solution called potassium iodide. Lead will react with potassium iodide to form a yellow precipitate, which can help identify the metal as lead.
Lead is a poor metal and (or) a metalloid: it has some amphoteric properties as well, like bismuth or arsenic. It has some fine metallic properties though.
They test for lead in blood because lead is a toxic metal, and if it gets into your bloodstream, it could be fatal, and even cause death. They test for lead in blood so you can survive and not die from lead poisoning, because lead is a toxic metal that basically poisons you.
NO!!! It is a white solid compound. Car batterty terminals may turn white, this is lead sulphate. It comes from a combination of lead from the lead plates in the battery and sulphuric acid, the battery liquid.
Lead is a chemical element not a mixture.

Lead oxide is not a metal. Why?Lead is metal by itself, lead oxide is metal oxide, meaning it is a chemical compound that contains at least one atom of oxygen (thus oxide) and one other element (being a metal oxide, that one other element has to be metal, in this case lead).
One can identify a metal drill bit by its shiny appearance, hardness, and ability to cut through metal materials. Metal drill bits are typically made of materials like high-speed steel or cobalt, and they often have a sharp point for drilling into metal surfaces.

Yes, lead is a metal.

Lead is a soft ductile metal.

Pencil "lead" is not really lead, the metal - Pb. Pencils are made with graphite which is a mineral, an insulator.
No, lead is a metal and metal is not bio degradable.
