General Chemistry 1 Exam 1 | Latest Update | 2024/2025 | Rated A+ What is the role of the Pauli exclusion principle in determining the electron configuration of atoms? The Pauli exclusion principle states that no two electrons in an atom can have the same set of quantum numbers, which helps determine the unique electron configuration and arrangement in orbitals.

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 increases. (holds onto the electrons tighter) Big ...
