Formal Charges

40.7K
In some cases, there are seemingly more than one valid Lewis structures for molecules and polyatomic ions. The concept of formal charges can be used to help predict the most appropriate Lewis structure when more than one reasonable structure exists.

Ions and Ionic Charges

79.4K
In ordinary chemical reactions, the nucleus — which contains the protons and neutrons of each atom and thus identifies the element — remains unchanged. Electrons, however, can be added to atoms by transfer from other atoms, lost by transfer to other atoms, or shared with other atoms. The transfer and sharing of electrons among atoms govern the chemistry of the elements. During the formation of some compounds, atoms gain or lose electrons to form electrically charged particles called...

Atomic Radii and Effective Nuclear Charge

62.3K
The elements in groups of the periodic table exhibit similar chemical behavior. This similarity occurs because the members of a group have the same number and distribution of electrons in their valence shells.

Gas Exchange and Transport

77.1K
Gas exchange, the intake of molecular oxygen (O2) from the environment and the outflow of carbon dioxide (CO2) into the environment, is necessary for cellular function. Gas exchange during respiration occurs largely via the movement of gas molecules along pressure gradients. Gas travels from areas of higher partial pressure to areas of lower partial pressure. In mammals, gas exchange occurs in the alveoli of the lungs, which are adjacent to capillaries and share a membrane with them.

Kinetic Molecular Theory and Gas Laws Explain Properties of Gas Molecules

37.6K
The test of the kinetic molecular theory (KMT) and its postulates is its ability to explain and describe the behavior of a gas. The various gas laws (Boyle’s, Charles’s, Gay-Lussac’s, Avogadro’s, and Dalton’s laws) can be derived from the assumptions of the KMT, which have led chemists to believe that the assumptions of the theory accurately represent the properties of gas molecules.

From lightning during thunderstorms to electronic devices, the phenomenon of electromagnetism is all around us. The electromagnetic force is one of the four fundamental forces of nature. It has been known to humanity in various forms for thousands of years. For example, the ancient Greek philosopher Thales of Miletus recorded his experiments on static electricity using amber and fur in the sixth century BC.
The English physicist William Gilbert studied the phenomenon of static electricity in...

Summary

Collisional charging in granular gases significantly impacts particle clustering. Electrostatic forces, not just dissipation, alter cluster size, shape, and growth rates, promoting aggregation by reducing particle diffusion.

Area of Science:

  • Physics
  • Materials Science
  • Statistical Mechanics

Background:

  • Neutral dielectric grains can acquire charges through collisions, leading to long-range electrostatic interactions.
  • Granular gases, composed of particles, exhibit complex behaviors influenced by inter-particle forces and energy dissipation.

Purpose of the Study:

  • To investigate the influence of electrostatic interactions from collisional charging on the clustering dynamics of a granular gas.
  • To compare the clustering behavior of charged granular gases with that of neutral granular gases.

Main Methods:

  • Three-dimensional molecular dynamics simulations of a dilute, freely cooling granular gas.
  • Modeling viscoelastic particles that exchange charges during collisions.
  • Mean-field calculations using Smoluchowski's equation.

Main Results:

  • Electrostatic interactions due to collisional charging alter cluster size, morphology, and growth rates compared to neutral granular gases.
  • The average cluster size exhibits power-law growth, with a larger exponent in charged gases.
  • The ratio of Coulomb to kinetic energy affects cluster growth crossover time but not the overall growth rate.

Conclusions:

  • Electrostatic interactions play a crucial role in granular gas clustering, modifying aggregation dynamics beyond simple dissipation.
  • Suppression of particle diffusion by electrostatic forces enhances the aggregation process.
  • The findings provide insights into the collective behavior of charged granular systems.
