Thomson's e/m Experiment

Thomson's e/m Experiment

In a beam of charged particles created by a heated cathode, the particles move at different speeds. However, many applications need a beam with uniform particle speeds. An arrangement known as a velocity selector uses electric and magnetic fields to pick particles with a particular speed from the beam.
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The magnetic...

Electron Behavior

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,...

Electron Configurations

Electron Configurations

Electron configurations and orbital diagrams can be determined by applying the Aufbau principle (each added electron occupies the subshell of lowest energy available), Pauli exclusion principle (no two electrons can have the same set of four quantum numbers), and Hund’s rule of maximum multiplicity (whenever possible, electrons retain unpaired spins in degenerate orbitals).
The relative energies of the subshells determine the order in which atomic orbitals are filled (1s, 2s, 2p, 3s, 3p, 4s,...

Lewis Structures of Molecular Compounds and Polyatomic Ions

To draw Lewis structures for complicated molecules and molecular ions, it is helpful to follow a step-by-step procedure as outlined:

Sources and Properties of Electric Charge

Sources and Properties of Electric Charge

All objects we see around us consist of atoms, which combine to form molecules. The lightest element in the universe is hydrogen, and a hydrogen atom consists of a positively charged proton and a negatively charged electron. The magnitude of charge that a proton and an electron carry are the same, and it is the fundamental unit of charge. In SI units, it is 1.602 times 10-19 coulomb.
Most atoms additionally constitute another fundamental particle, the neutron. It carries no electrical charge. A...

Crystallography

Background:

Direct Methods are crucial for solving the phase problem in diffraction imaging.
Applying Direct Methods to swift electron scattering is challenging due to complex scattering phenomena.

Purpose of the Study:

To identify and define conditions under which Direct Methods are applicable to swift electron scattering.
To expand the utility of Direct Methods in electron diffraction analysis.

Main Methods:

Analysis of kinematical and dynamical scattering regimes in electron diffraction.
Investigation of specific electron channeling conditions (1s channeling).
Exploration of intensity mapping between kinematical and dynamical scattering.

Main Results:

Identified four configurations where Direct Methods are viable for swift electrons: standard kinematical scattering, 1s channeling, intensity-preserving mappings, and single-atom scattering dominance.
Demonstrated statistical correctness of kinematical scattering under 1s channeling.

Conclusions:

Direct Methods can be effectively applied to swift electron scattering in identified scenarios.
These findings broaden the scope of Direct Methods for structural determination in electron microscopy.
