Lead does not burn in the traditional sense like wood or paper. Instead, it oxidizes in the presence of oxygen. The reaction is as follows:

2Pb (s) + O2 (g) → 2PbO (s)

Where:

* Pb is the chemical symbol for lead

* O2 is the chemical formula for oxygen

* PbO is the chemical formula for lead oxide (also known as litharge)

This reaction produces lead oxide, a solid substance that forms a thin layer on the surface of lead. This layer can be further oxidized to form lead dioxide (PbO2).

It's important to note that burning lead is a hazardous process. The fumes produced can be toxic and lead oxide can be harmful if inhaled.
