| Question | Answer |
|---|---|
| electromagnetic spectrum | includes all forms of electromagnetic radation with differing wavelengths and frequencies |
| Planck's constant | has the value of 6.626 * 10 -34 Js, where j is a symbol forjoule and s in seconds |
| photoelecric effect | phenomenon in which photeoelectrons are emitted from a metal's surface when light of a certain frequency shines on the surface |
| continuous spectrum | shines with a connected series of colors, each with unique wavelengths and frequiences |
| atomic emission spectrum | set of frequiences of light emitted by the atoms of a specific element |
| Heisenburg Uncertainty Principle | state that it fundamentally impossible to know precisley both the velocity and position of a particle at the same time |
| electron configuration | arrangement of electrons in a atom |
| aufbau principle | states that each electron occupies the lowest energy orbital avaibable |
| Pauli exclusion principle | states that a maxium of two electrons, with opposite spins, may occupy a single atomic orbital |
| Hund's rule | single electrons with the same spin must occupy each equal energy orbital before additional electrons are added |
