Laws/Rules/Principles Flashcards
Aufbau Principle
Electrons fill lower-energy atomic orbitals before filling higher-energy ones.
Pauli’s Exclusion Principle
No two electrons in the same atom can have identical values for all four of their quantum numbers.
Bohr’s Model
Electrons orbit the nucleus at fixed energy levels.
Hunds Rule
The electrons enter an empty orbital before pairing up.
Louis De Broglie
Particles, such as electrons, could be described not only as particles but also as waves.
Electromagnetic (Ampere law)
A moving or spinning electric charge creates a magnetic field.
Lattice Energy
Change in energy that takes place when gaseous ion form an ionic solid.
Hydrogen Bonds
(H-F, H-O, H-N) - Strongest force.
Coulomb’s Law
The closer two charges are the stronger the force is.
Intermolecular Forces
The attraction between molecules.
Spectrometry
Each compound absorbs or transmits light over a certain range of wavelengths.
