Ionization Energy03:12

Ionization Energy

43.6K
The amount of energy required to remove the most loosely bound electron from a gaseous atom in its ground state is called its first ionization energy (IE1). The first ionization energy for an element, X, is the energy required to form a cation with 1+ charge:

Types Of Collisions - I

9.5K
When two objects come in direct contact with each other, it is called a collision. During a collision, two or more objects exert forces on each other in a relatively short amount of time. A collision can be categorized as either an elastic or inelastic collision. If two or more objects approach each other, collide and then bounce off, moving away from each other with the same relative speed at which they approached each other, the total kinetic energy of the system is said to be conserved. This...

Types of Collisions - II

10.1K
When two or more objects collide with each other, they can stick together to form one single composite object (after collision). The total mass of the object after the collision is the sum of the masses of the original objects, and it moves with a velocity dictated by the conservation of momentum. Although the system's total momentum remains constant, the kinetic energy decreases, and thus such a collision is an inelastic collision. Most of the collisions between objects in daily life are...

Electron Transport Chains01:28

Electron Transport Chains

113.2K
The final stage of cellular respiration is oxidative phosphorylation that consists of two steps: the electron transport chain and chemiosmosis. The electron transport chain is a set of proteins found in the inner mitochondrial membrane in eukaryotic cells. Its primary function is to establish a proton gradient that can be used during chemiosmosis to produce ATP and generate electron carriers, such as NAD+ and FAD, that are used in glycolysis and the citric acid cycle.
The ETC is comprised of...

Electron Carriers01:24

Electron Carriers

92.2K
Electron carriers can be thought of as electron shuttles. These compounds can easily accept electrons (i.e., be reduced) or lose them (i.e., be oxidized). They play an essential role in energy production because cellular respiration is contingent on the flow of electrons.
Over the many stages of cellular respiration, glucose breaks down into carbon dioxide and water. Electron carriers pick up electrons lost by glucose in these reactions, temporarily storing and releasing them into the electron...

Electron Affinity03:07

Electron Affinity

43.8K
The electron affinity (EA) is the energy change for adding an electron to a gaseous atom to form an anion (negative ion).

Area of Science:

  • Atomic and Molecular Physics
  • Collision Physics
  • Quantum Chemistry

Background:

  • Understanding ion-atom collisions is essential for plasma physics and materials science.
  • Accurate cross-section data is needed for modeling and simulation.

Purpose of the Study:

  • To calculate total cross sections for H and H- formation and electron production in H+ + Ar collisions.
  • To compare results from two distinct computational methods across different energy regimes.

Main Methods:

  • Switching-classical-trajectory-Monte Carlo (s-CTMC) method for E > 10 keV.
  • Block-diagonalization technique for calculating molecular autoionizing states.

Main Results:

  • The s-CTMC method accurately predicted H- formation cross sections, aligning well with experimental data.
  • Both methods yielded good agreement with experimental data for electron and H- production cross sections.
