Electron Distribution Flashcards
Uses the symbols at the orbitals and the number of electrons written as superscripts
Electron Configuring/Configuration
Consists of boxes and arrows that represent the orbitals and the electrons, respectively
Orbital Diagram
Means that the atom’s electrons occupy the lowest possible energy levels
Ground state
Three general rules that representing electron distribution
- Aubfau Principle
- Pauli Exclusion
- Hund’s rule of maximum multiplicity
What do the up and down orientations of the arrows represent?
The two magnetic spins of the electrons
States that electrons should occupy first the orbitals with lower energy before those with higher energy
Aufbau principle
States that no two electrons in an atom can possess the same set of quantum numbers
Pauli Exclusion Principle
Emphasizes the significance of the spin quantum numbers
Pauli Exclusion Principle
Suggests that the most stable arrangement of electrons in subshells is the one with the greatest number of parallel spins
Hund’s rule of maximum multiplicity
Each orbital in a subshell is singly occupied before paring of electrons occurs
Hund’s rule of maximum multiplicity
- Metal to non-metal
- Transfer of elevtron
Ionic
- Non metal to non metal
- Sharing of electron
Covalent
Outermost electron
Valence Electron
States that atoms tend to form compounds in ways that give tgem light valence electron and thus the electron configuration of a noble gas
Octet Rule
Is a measure of from strongly atoms attract bonding electrons themselves.
Electronegativity
