The atomic number of lead is 82. That tells us that electrically neutral lead has 82 protons and 82 electrons. The three stable isotopes of lead are 206 Pb, 207 Pb, and 208â¦ Pb. These isotopes have 124, 125, and 126 neutrons per each atom, respectively.
The melting point of lead in Celsius is 327.46o. Temperature Fahrenheit = Temperature Celsius(1.80) + 32 Temperature Fahrenheit = (327.46o C)(1.80) + 32 = 621.43o Fahren â¦ heit ==.elting temperature is the point where a substance is reduced to a liquid (this is the state it changes to). the usual melting point of substances is 100 degrees or higher. â¦   thank you for answering!! 6 people found this useful. 1  The Periodic Table of Elements Life is sustained by a number of chemical elements.
