Question | Answer |
---|---|
electromagnetic spectrum | includes all forms of electromagnetic radiation with differing wavelengths and frequencies. |
Planck's constant | has a value of 6.626 x 10 -34 J s, where J is a symbol for joule and s is seconds. |
photoelectric effect | phenomenon in which photoelectrons 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 frequencies. |
atomic emission spectrum | set of frequencies of light emitted by the atoms of a specific element. |
Heisenburg Uncertainty Principle | states that it's fundamentally impossible to know precisely both the velocity and position of a 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, may occupy a single atomic orbital. |
Hund's rule | single electrons eith the same spin must occupy each equal energy orbital before additional electrons are added. |
