An atomic anion with a charge of -1 has the following electron configuration: [{MathJax fullWidth='false' Ne 3s^2 3p^3 }]. What is the identity of the atom?Electron Configuration :The electron configuration of an element is the process of arranging the electrons of...
is an electron transition process resulting from the inter- and intrastate transitions of electrons in an excited atom when electrons, ions, photons, or neutral atoms interacts with an atom with an energy exceeding that necessary to remove an inner-shell electron (K, L, M) from the atom. ...
The band theory suggests that a single atom has discrete energy levels. With an increase in the number of atoms in solids (conduction electron number N), atomic levels may change into a discrete band (Figure 1.9). Macroscopic objects contain an unlimited number of atoms; that is, for the ...

Interpretation: Hydrogen orbitals in the increasing order of energy should be listed. Concept Introduction: In the ground state of an atom, an electron enters the orbital with lowest energy first and subsequent electrons are fed in the order of increasing energie...
(Fig.2c), whereas the electron distribution becomes delocalized following modification with Sb2Se3(Fig.2d). C-V profiling and DLCP measurements reveal an order of magnitude lower interfacial defect density (2 × 1011 cm−2) than in the control devices (2 × 1012 cm−2) ...
pathways called orbitals, an idea that was put forth by Erwin Schrödinger, an Austrian physicist, in the 1920s. Today, this model is known as the quantum model or the electron cloud model. The inner orbitals surrounding the atom are spherical but the outer orbitals are much more ...
Twisted bilayer graphene (TBG) has taken the spotlight in the condensed matter community since the discovery of correlated phases. In this work, we study heterostructures of TBG and hexagonal boron nitride (hBN) using an atomistic tight-binding model tog
