CEM 141 EXAM 3 MSU

Ionization Energy Ans: energy required to remove an electron from an atom in the gas phase Left Side Electrons Ans: 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? Ans: 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 electrons ...

T/F: Covalent bonds are present only when atomic orbitals interact constructively. Ans: True. Binding in Diamond Ans: Each carbon forms 4 bonds to 4 identical carbons; tetrahedral; sp3 Valence Bond Theory Ans: The idea that covalent bonds are formed when orbitals of different atoms overlap. T/F: Electrons are localized in molecular orbital. Ans: False T/F: Electrons are localized in Valence Bond. Ans: True T/F: When the hybrid orbitals combine, there is a large gap between the bondin...
