  • What are Atomic Orbitals? - BYJUS
    What are the 4 atomic orbitals? There are four types of orbitals that you should know (sharp, principal, diffuse and fundamental) with s, p, d and f Few variations of orbitals occur within each shell of an atom
  • What are Electron Configurations? - BYJUS
    What are Electron Configurations? The electron configuration of an element describes how electrons are distributed in its atomic orbitals Electron configurations of atoms follow a standard notation in which all electron-containing atomic subshells (with the number of electrons they hold written in superscript) are placed in a sequence
  • What are Quantum Numbers? - BYJUS
    Quantum numbers can be used to describe the trajectory and the movement of an electron in an atom The quantum numbers of all the electrons in a given atom, when combined, must comply with the Schrodinger equation Table of Content What are Quantum Numbers? Recommended Videos on Quantum Numbers Principal Quantum Number Azimuthal Quantum Number Magnetic Quantum Number Electron Spin Quantum
  • What Is Molecular Orbital Theory? - BYJUS
    What Is Molecular Orbital Theory? The molecular orbital theory (often abbreviated to MOT) is a theory on chemical bonding developed at the beginning of the twentieth century by F Hund and R S Mulliken to describe the structure and properties of different molecules The valence-bond theory failed to adequately explain how certain molecules contain two or more equivalent bonds whose bond
  • What is the Aufbau Principle? - BYJUS
    A diagram illustrating the order in which atomic orbitals are filled is provided below Here, ‘n’ refers to the principal quantum number and ‘l’ is the azimuthal quantum number The Aufbau principle can be used to understand the location of electrons in an atom and their corresponding energy levels
  • BYJUS
    Fig: Energy variation for various orbitals Factors affecting the energy of orbitals: For a given value of the principal quantum number, the s orbital electron will be more tightly bound to the nucleus than the p orbital electron, which is more tightly bound in comparison to a d orbital electron
  • What are Pi Bonds? - BYJUS
    What are Pi Bonds? Pi bonds are chemical bonds that are covalent in nature and involve the lateral overlapping of two lobes of an atomic orbital with two lobes of another atomic orbital that belongs to a different atom Pi bonds are often written as ‘𝛑 bonds’, where the Greek letter ‘𝛑’ refers to the similar symmetry of the pi bond and the p orbital The two orbitals which are
  • Degenerate orbitals definition: - BYJUS
    Degenerate Orbitals Example: Explanation of Degenerate Orbitals with Diagram What is the Aufbau Principle? It states that in the ground state of an ion or an atom, the atomic orbitals of the electrons fill the lowest available energy levels before they occupy the higher levels For instance, 2s subshell is filled after the 1s shell is occupied
