Chem Vocab Flashcards
The quantum number that indicates the shape of an orbital
Angular Momentum Quantum Number
structure of successive elements obtained by adding one proton to the nucleus and one electron to the lowest energy orbital available
Aufbau Principle
Arrangements of electrons in a atom
Electron Configuration
Radiation associated with electric and magnetic field
Electromagnetic Radiation
Atom has more energy that it has at ground state
Excited State
Lowest energy state of a quantized system
Ground state
Determining both position and velocity of electron or any other particle simulations is impossible
Heisenberg Uncertainty Principle
Electron containing main energy level with the highest number
Highest Occupied Level
Every Orbital subshell is singly occupied with an electron before any one orbital is doubly occupied
Hund’s Rule
Specific atoms that are in core orbitals by quite high binding energy
Inner Shell Electrons
corresponds to alignment of angular momentum component with a magnetic field
Magnetic Quantum Number
outer main energy level fully occupied, in most cases by 8 electrons
Noble Gas Configuration
One of elements of group 18 in periodic table; unreactive
Noble Gases
Region in atom that has high probability of finding electrons
Orbital
Two particles of certain class cannot have exactly same energy state
Pauli Exclusion Principle
