List the numbers of protons, neutrons, and electrons in chlorine-18. (3 points) write the electron configuration for a chlorine atom. calculate the total number of electrons in each energy level and state which energy levels are not full. (3 points) what are the three rules that govern the filling of atomic orbitals by electrons? be sure to describe each one, not just name it. (3 points) there are four isotopes of lead and their relative abundance listed below. use this information to calculate the approximate atomic mass of lead. show all work (4 points) 82 protons, 122 neutrons, 1.4% 82 protons, 125 neutrons, 22.1% 82 protons, 124 neutrons, 24.1% 82 protons, 126 neutrons, 52.4% define first ionization energy and describe the trends within groups and across periods in the periodic table. provide examples. (4 points) write the electron configuration for the metalloid in period 3. include the name of the element. (3 points)
