From Wikipedia: In chemistry, a metal (Greek: Metallo, Μέταλλο) is an element, compound, or alloy characterized by high electrical conductivity. In a metal, atoms readily lose electrons to form positive ions (cations); those ions are surrounded by delocalized electrons, which are responsible for the conductivity. The thus produced solid is held by electrostatic interactions between the ions and the electron cloud, which are called metallic bonds. From me:
If an element shows these characteristics, it is a metal. Calcium shows these characteristics. Therefore, Calcium is a metal.
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.
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.
When carbon reacts with lead oxide, it produces lead metal and carbon dioxide as byproduct.
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 being less electropositive will be given out

Yes, lead is a metal.
Lead metal
Lead is a soft ductile metal.
Lead is a soft ductile metal.
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).
Pencil "lead" is not really lead, the metal - Pb. Pencils are made with graphite which is a mineral, an insulator.
Lead is a metal.
No, lead is a metal and metal is not bio degradable.
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.
No, lead is not a ferrous metal. Ferrous metals are those that contain iron, while lead is a non-ferrous metal.
