Electronic structure is the state of motion of electrons in an electrostatic field created by stationary nuclei. The term encompass both the wavefunctions of the electrons and the energies associated with them. Atomic Orbitals This page discusses atomic orbitals at an introductory level. It explores s and p orbitals in some detail, including their shapes and energies. d orbitals are described only in terms of their energy, and f orbitals are only mentioned in passing. Bohr Diagrams of Atoms and Ions Bohr diagrams show electrons orbiting the nucleus of an atom somewhat like planets orbit around the sun. In the Bohr model, electrons are pictured as traveling in circles at different shells, depending on which element you have. Electronic Configurations The electron configuration of an atom is the representation of the arrangement of electrons distributed among the orbital shells and subshells. Commonly, the electron configuration is used to describe the orbitals of an atom in its ground state, but it can also be used to represent an atom that has ionized into a cation or anion by compensating with the loss of or gain of electrons in their subsequent orbitals. Many of the physical and chemical properties of elements can be correlated to electro Basic Electronic Structure of Atoms Case Study: Electron Configuration of Mn vs. Cu d-orbital Occupation and Electronic Configurations Electronic Configurations Intro Electronic Structure and Orbitals Hund's Rules Pauli Exclusion Principle Spin Pairing Energy Spin Quantum Number The Aufbau Process The Octet Rule The Order of Filling 3d and 4s Orbitals Evaluating Spin Multiplicity Spin-multiplicity value and its corresponding spin state was first discovered by Friedrich Hund in 1925. The formula which is generally used for the prediction of spin multiplicity value is (2S+1). Hydrogen's Atomic Emission Spectrum This page introduces the atomic hydrogen emission spectrum, showing how it arises from electron movements between energy levels within the atom. It also explains how the spectrum can be used to find the ionization energy of hydrogen. Magnetic Behavior of Diatomic Species Predicting the Bond-Order of Diatomic Species In this article text based learning approaches have been highlighted by innovative and time economic way to enhance interest of students’ who belong to paranoia zone in chemical bonding. In this pedagogical survey, I have tried to hub one time economic pedagogy by including four (04) new formulae in the field of chemical education. This article explores the results and gives implications for context based teaching, learning and assessment in a time economic way.
