The Quantum-Mechanical Model of an Atom02:45

The Quantum-Mechanical Model of an Atom

Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra. Schrödinger...

Aromatic Hydrocarbon Cations: Structural Overview

Cycloheptatriene is a neutral monocyclic unsaturated hydrocarbon that consists of an odd number of carbon atoms and an intervening sp3 carbon in the ring. The three double bonds in the ring correspond to 6 π electrons, which is a Huckel number, and therefore satisfies the criteria of 4n + 2 π electrons. However, the intervening sp3 carbon disrupts the continuous overlap of p orbitals. As a result, cycloheptatriene is not aromatic.
Removing one hydrogen from the intervening CH2 group with both...

Electron Behavior

Electrons are negatively charged subatomic particles that are attracted to an orbit around the positively-charged nucleus of an atom. They reside in locations that are associated with energy levels called shells and are further organized into sub-shells and orbitals within each shell.Electrons Orbit the NucleusElectrons are found in specific locations outside of the nucleus. The shell in which an electron resides indicates the general energy level of the electron: those closer to the nucleus...

Electron Behavior

Electrons are negatively charged subatomic particles attracted to and orbit around the positively-charged nucleus of an atom. They reside in spaces associated with energy levels called shells and are further organized into subshells and orbitals within each shell.
Electrons Orbit the Nucleus
Electrons are found in specific locations outside of the nucleus. The shell in which an electron resides indicates the general energy level of the electron: those closer to the nucleus have less energy,...
Aldehydes and Ketones with Water: Hydrate Formation01:20

Aldehydes and Ketones with Water: Hydrate Formation

An oxygen-based nucleophile, like water, can undergo addition reactions with aldehydes and ketones. The reaction leads to the formation of hydrates, also referred to as 1,1-diols or geminal diols.
The formation of hydrates is a reversible reaction. Hydrate formation is influenced by steric and electronic factors accompanying the alkyl substituents on the carbonyl group: The rate of hydrate formation increases with a decrease in the number of alkyl groups attached to the carbonyl carbon. Hence,...

Summary
This summary is machine-generated.

The aqueous electron may not form a cavity in water as previously thought. However, a closer look at the theoretical model shows discrepancies with established data and fundamental theories.

Area of Science:

  • Physical Chemistry
  • Theoretical Chemistry
  • Computational Chemistry

Background:

  • The established paradigm suggests the aqueous electron occupies a cavity in liquid water.
  • Larsen et al. proposed a new model challenging this long-held view.

Discussion:

  • The theoretical model by Larsen et al. presents predictions that diverge significantly from established benchmarks.
  • The model's behavior shows qualitative differences compared to Hartree-Fock theory, its foundational basis.

Key Insights:

  • Re-evaluation of the Larsen et al. model indicates potential inconsistencies with experimental and theoretical standards.
  • The model's departure from Hartree-Fock theory warrants further investigation into its validity.

Outlook:

  • Further theoretical and computational studies are needed to validate or refute the proposed model.
  • Clarifying the behavior of the aqueous electron is crucial for understanding electron transfer processes in aqueous solutions.
