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.
Protons have a positive charge while electrons have a negative charge. In order to form a neutral (no charge) atom there must be the same number of protons as electrons. Therefore there are 17 protons since there are 17 electrons. In an atom the number of protones are equal to the number of electrons. therefore that atom will be neutral in charge. So, a neutrally charged clorine atom is having 17 electrons & 17 protons. Access hundreds of thousands of answers with a free trial.
