Explanation: The number of electrons and protons are given by the atomic number of the element. Lead have 82 electrons and 82 protons. The number of neutrons are given by the difference between the mass number and atomic number. For lead number of neutrons = 207 - 82 = 125. Learn more about: Lead has been known since ancient times. It is sometimes found free in nature, but is usually obtained from the ores galena (PbS), anglesite (PbSO 4), cerussite (PbCO 3) and minum (Pb 3 O 4).Although lead makes up only about 0.0013% of the earth's crust, it is not considered to be a rare element since it is easily mined and refined.
