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...

General Chemistry Exam 1 Review Questions And Answers | Latest Update | 2024/2025 | 100% Pass What is the primary difference between an ionic bond and a covalent bond in terms of electron distribution? In an ionic bond, electrons are transferred from one atom to another, resulting in the formation of ions, whereas in a covalent bond, electrons are shared between atoms. How can you determine the empirical formula of a compound given its percent composition? The empirical formula...

*Chromatography* - Ans .-Chromatography is a method used by chemists to separate out mixtures. -Chromatography works because different dyes move up the paper and different rates. -Some will stick to the paper and others will dissolve more readily in the solvent and travel more quickly. -You can com[are different chromatograms to work out what dyes are in the unknown substance. *Ionic Bonding* - Ans .-In ionic bonding, atoms lose or gain electrons to formed charged particles which are...
