electrons and waves
Question | Answer |
---|---|
electromagnetic spectrum | includes all forms of electromagnetic radiation with differing wavelengths and frequencies |
planks constant | has a value of 6.626x 10 -34 J's where j is a symbol for joule and s is seconds |
photoelectric effect | phenomenon in which photo electrons are emitted from a metal's surface when light of a certain frequency shines on the surface |
continuous spectrum | shines with 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 | states that it 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 2 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 |
