Did you know?
WebHow many protons, neutrons, and electrons are in (a) the cation 204 Pb 2+ and (b) the anion 37 Cl-? Solution: (a) We know from the periodic table that lead has 82 protons. The mass number 204 – 82 protons = 122 neutrons. From the charge, we know that the cation has 2 more protons than electrons, so there are 82 protons – 2 = 80 electrons. Web20 feb. 2024 · Look in the periodic table and find iron (Fe). It has an atomic # = 26 and atomic mass 56. Protons = 26. Electrons = 26. Neutrons = 56 - 26 = 30 neutrons. For 58F e, the atomic mass is 58, but it still has 26 protons. So, number of neutrons = 58-26 = 32 neutrons. For 58 Fe 2-, the atomic mass is 58, it has 26 protons, but now it 28 …
