Auger effect print that page

environment in which the atom was located. Auger electron spectroscopy involves the emission of Auger electrons by bombarding a sample with either X-rays or energetic electrons and measures the intensity of Auger electrons as a function of the Auger electron energy. The resulting spectra | 2011/4/27 0:40:54

Secondary electrons print that page

Secondary electrons are also the main means of viewing images in the scanning electron microscope (SEM). The range of secondary electrons depends on the energy. Plotting the inelastic mean free path as a function of energy often shows characteristics of the "universal curve" [ 1 ] familiar | 2011/4/14 21:28:58

Delta ray print that page

Melbourne , Australia . [ edit ] Characteristics A delta ray is characterized by very fast electrons produced in quantity by alpha particles or other fast energetic charged particles knocking orbiting electrons out of atoms . Collectively, these electrons are defined as delta radiation | 2010/9/26 19:41:16

Core electron print that page

the environment of the atom when in the solid state . Therefore on the contrary of the valence electrons , the core electrons usually play a secondary role on chemical bonding and reactions and their main role is to screen the positive charge of the atomic nucleus. In transition metals | 2011/2/24 13:04:14

Electronic band structure print that page

edit ] Why bands occur in materials See also: Conduction band , Valence band , and Bandgap The electrons of a single isolated atom occupy atomic orbitals , which form a discrete set of energy levels. If several atoms are brought together into a molecule, their atomic orbitals split, as | 2011/5/24 8:54:27

Non-bonding orbital print that page

A non-bonding orbital , also known as non-bonding molecular orbital (NBMO), is a molecular orbital whose occupation by electrons neither increases nor decreases the bond order between the relevant atoms . Non-bonding orbitals are the equivalent in molecular orbital theory of the lone pairs | 2010/9/24 23:35:09

Delocalized electron print that page

In chemistry, delocalized electrons are electrons in a molecule or solid metal that are not associated with a single atom or one covalent bond . [ 1 ] Delocalized electrons are contained within an orbital that extends over several adjacent atoms. Classically, delocalized electrons | 2011/5/24 11:32:01

Spin states (d electrons) print that page

additional electron into an e g orbital at an energy cost of Δ. If the energy required to pair two electrons is greater than the energy cost of placing an electron in an e g , Δ, high spin splitting occurs. If the separation between the orbitals is large, then the lower energy orbitals | 2011/4/20 8:09:38

Pi bond print that page

in contact through two areas of overlap. Pi-bonds are more diffuse bonds than the sigma bonds. Electrons in pi bonds are sometimes referred to as pi electrons . Molecular fragments joined by a pi bond cannot rotate about that bond without breaking the pi bond, because rotation involves destroying | 2011/4/18 23:24:06
