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. How do isotopes of the same element differ from each other? Isotopes of the same element have the same number of proton...

DAT General Chemistry Questions and Answers | Latest Update | 2024/2025 | Graded A+ How is the periodic table arranged to reflect the properties of elements? The periodic table is arranged by increasing atomic number, with elements grouped into columns (groups) and rows (periods) that reflect similar chemical properties and trends in atomic structure. What is the role of a chemical equation in representing a chemical reaction? A chemical equation represents a chemical reaction by...

Chem 120 exam guide highly recommended Degenerate Degenerate orbitals = 2+ orbitals w/equal energy (ex= 2p) -One electron goes into each degenerate orbital before any pairing occurs Requires energy 1s-> 2s requires energy -energy levels are dictated by principle quantum number (n) -need more energy for an electron to move away from the nucleus -energy levels get closer together as they increase in quantum number Orbitals B/c 2s and 2p orbitals have the same principal quant...
