Ionization energy Study guides, Class notes & Summaries

CEM 141 MSU Exam 3 Latest Update Graded A+ Ionization Energy energy required to remove an electron from an atom in the gas phase Left Side Electrons have weaker attractions to remove electrons *easier to remove electrons from the left side of the table than the right side* Does it take MORE or LESS energy to remove an electron from Li than from Na? MORE Why? Because as we move down a group, the orbitals become larger and weaker. While going across the effective nuclear charge in...
