| Is wavelength and frequency directly related or inversely? | Inversely |
| Democritus | Said the world is made up of empty space and basic particle called the "atom" |
| Atom | "indivisible" in Greek |
| Aristotle | Didn't believe in atoms believed in continuous flowing matter called "hyle" |
| Law of definite porportions | A compound contains elements in the same prportion by mass regardless of the size of the sample |
| Law of mulitple porportions | Ratio of masses of one element to another element in a compound can always be expressed as small whole numbers |
| Atom | Smallest particle of an element that retains chemical properties of that element |
| J.J. Thomson | Cathode rays are negatively charged particles-electrons are found in all atoms |
| Millikan | Measured the charge of the electron |
| Rutherford | Discovered the nucleus and made the planetary model |
| Isotopes | Atoms of the same element that have different masses |
| Electromagnetic Radiation | A form of energy that exhibits wave-like behavior |
| Quantum | Minimum energy that is either lost or gained by an atom |
| Max Planck | German physicist said energy equals the constand times the frequency |
| How is energy and frequency related? | Directly |
| Gound state | lowest enegry state for the atom |
| Excited sate | higher energy state once e- has absorbed energy |
| Bohr Model | tried to prove that electrons can circle the nucleus in only specific paths |
| DeBroglie | Combined Planks & Ensteins equations to prove that particles can have wave properties |
| wavelength=h/mv | DeBroglie |
| Heisenberg's Uncertainty Principle | State's you can't pinpoint a location of e- |
| Principle Quantum Number (n) | corresponds to the energy level |
| Angular momentum Quantum Number ( l ) | energy states within each level-sublevel |
| Magnetic Quantum Number (m) | orbitals--> space occupied by 2 e- |
| Spin Quantum Number (s) | Two e- located in the same orbital will spin in opposite directions |
| Pauli Exclusion Principle | No 2 e- in an atom have the same set of 4 quantum numbers |
| Aufbau Principle | e- occupy the lowest energy orbital possible |
| Hund's Rule | Orbitals of equal energy are occupied b 1 e- follwed by a 2nd e- after each has 1 e- |
| How many orbitals are in the "d" sublevel? | 5 |
| What is the maximum number of electrons in the 4th energy level? | 32 |
| What is the first energy level to have a "d" sublevel? | 3rd |
| How many orbitals are in the "f" sublevel? | 7 |
| What is the maximum number of electrons in the "f" sublevel? | 14 |
