Ionization Energy - Answer-energy required to remove an electron from an atom in the gas phase Left Side Electrons - Answer-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? - Answer-MORE Why? Because as we move down a group, the orbitals become larger and weaker. While going across the effective nuclear charge increases. (holds onto the ele...
