Question | Answer |
---|---|
electromagnetic spectrum | includes all forms of electromagnetic radiation with differing wavelengths and frequencies. |
Planck's constant | has value of 6.626 x 10 -34 J s, where J is symbol for joule and s is seconds |
photoelectric effect | phenomenon in which photoelectrons are emitted from a mental'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 frequencies |
atomic emission spectrum | set of frequencies of light emitted by the atoms of a specific element |
Heisenberg Uncertainty Principle | stats that it fundamentally impossible to know precisely both the velocity and position of particle at the same time |
electron configuration | arrangement of electrons in an atom |
aufbau principle | states that each electron occupies the lowest energy orbital available |
Pauli exclusion principle | states that a maximum of two electrons, with opposite spins, many 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 |
