ELECTRON CONFIGURATION, ORBITAL DIAGRAM, AND QUANTUM NUMBERS Flashcards
Electronic Orbitals
Regions within the atom in which electrons
have the highest probability of being found
Electron Configuration
how electrons are distributed in its orbitals
Orbitals
SPDF
S orbital
Sharp
P orbital
Principal
D orbital
Diffusion
F orbital
Fundamental
Aufbau Principle
electrons should occupy first the orbitals with lower energy before those
with higher energy
Pauli Exclusion Principle
no two electrons in an atom can
possess the same set of quantum
numbers or spin (bawal parehong up or down sa isang box)
Hund’s Rule of Maximum Multiplicity
every orbital in a subshell is occupied
with one electron before any orbital is
doubly occupied (all orbitals should have up spin before it has a down spin)
Noble Gas
Has entire outer electron shell, which makes it
non-reactive
Doesn’t need other elements to be stable
