| Lowest energy level (or state) of an atom | Ground State |
| Energy that travels through space as a joined wave of electrical and magnetic fields. | Electromagnetic Radiation [EMR] |
| Defined as waves or cycles per second. | Frequency |
| In summary, said we can’t know the exact location of the electron. | Heisenberg |
| Developed an equation that is the basis for the quantum theory | Schrödinger |
| Abbreviation for the principal quantum number (gives shell size) | n |
| Electrons in the highest ground state energy level are called -----electrons. | Vlence |
| The shape of the s-orbital can be described as this. | Spere |
| Word to describe single lone electron in an orbital | Unpaired |
| All electrons not in the highest occupied energy level | Inner Shell |
| The distance from peak-to-peak of 2 successive waves | Wavelength |
| s, p, d, and f are examples of these. | Shapes or Sublevels |
| Quantum number associated with the shape of an orbital | Angular Momentum Quantum Number [l] |
| In German Means "Building Up", electrons fill in lowest available energy level obrital, in sequence of "building up" | Aufbau principle |
| arrangement of electrons in a particular atom into specific orbitals | Electron Configuration |
| Orbitals in the same sublevel are all singly filled, before any are doubled, and when singly filled all have the same spin (all spin up or spin down) | Hund’s Rule |
| The electromagentic "thumbprint" of an atom, a unique sequence of spectral lines observed when light emitted from a pure elementals susbtance is diffracted into its component wavelengths | Line Emmission Spectrum |
| Quantum # that indicates orientation in space of an orbital relative to the nucleus (compared to X, Y, & Z axis) | Magnetic Quantum Number (m sub l) |
| Group 18 on the periodic table, the last column, has a full valence shell | Noble Gas Group |
| A shorthand method of expressing electron configuration notation using the elemental symbol of the preceding noble gas in brackets (e.g. [Ne]) and then only expressing the electrons higher in energy level in the standard electron configuration notation | Noble Gas Configuration |
| A 3-D shape that represents a solution to the Schrodinger Wave equation and indicates a region of space in which there is a high liklihood of finding an electron with a given set of 4 quantum numbers | Orbital |
| The concept that states no 2 electrons in atom can have all four quantum numbers be the same (i.e. for any electron there is a unique combination of the 4 quantum numbers that define it) | Pauli Exclusion Principal |
| This is one phenomenon that gives strong credence to the particle theory of light in that it explains that photons of EMR may be able to "knock" electrons out of metal atoms, generating an electrical current | Photo Electric Effect |
| The term that describes one particle (or quanta) of light [EMR] | Photon |
| A "packet" ; The mininimum amount of energy an electron (and atom) can emit or absorb | Quantum |
| A set of 4 numbers that represent solutions to Schrodingers wave function, that give information regarding electrons in an atom (analgous to an electrons zip code) | Quantum Numbers |
| The theory that describes an atom using applications of matter waves and the complex mathematics required to define them | Quantum Theory |
| Can be losely thought of as the direction of an electrons spin (CW or CCW), the fourth and final quantum number that has two values + and - 1/2 | Magentic Spin Quantum Number (m sub s) |
