Galena, a mineral consisting of lead sulfide, can be easily confused for lead or soot due to its metallic luster and dark coloration. However, galena is a naturally occurring mineral rather than a metal like lead.
Producing soot by burning something is a chemical change, but when it is deposited on metal (or anything else), that is a not a chemical change.See the Related Questions to the left for more information.
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.
Efficiency in an oil furnace can affect soot production in two ways. A more efficient furnace may burn oil more completely, leading to less soot production. On the other hand, if the furnace is not properly maintained or tuned, it can lead to incomplete combustion and higher levels of soot. Regular maintenance and proper settings are important to minimize soot production.
Aluminum is a metal, not to be confused with metalloid, even though it is touching the staircase of which all elements are metalloids.
Zinc was often confused with lead and tin due to their similar appearances. However, zinc has a higher melting point than lead and tin, and it does not oxidize easily like lead and tin.

Yes, lead is a 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).
Inhaling soot can lead to respiratory irritation, coughing, and shortness of breath. Long-term exposure to soot particles can increase the risk of developing respiratory diseases such as asthma, bronchitis, and even heart problems. It is important to avoid inhaling soot and seek medical attention if adverse symptoms occur.
Pencil "lead" is not really lead, the metal - Pb. Pencils are made with graphite which is a mineral, an insulator.
Lead is a metal.
