|---|---|---|---|---|---|
| electromagnetic radiation | a formof energy that exhibits wavelike behavior as it travels
🗑
|
||||
| wavelength | the shortest distance between equivalent points on a continuous wave
🗑
|
||||
| frequency | the number of waves that pass a given point per second
🗑
|
||||
| amplitude | the wave's height from the origin to a crest or from the origin to a trough
🗑
|
||||
| electromagnetic spectrum | encompasses all forms of electromagnetic radiation with the only difference in the types of radiation being their frequencies and wavelengths
🗑
|
||||
| quantum | the minimum amount of energy that can be gained or lost by an atom
🗑
|
||||
| Planck's constant | h which hasa value of 6.626X10^-34 J*s where J is the symbol for the joule
🗑
|
||||
| photoelectric effect | electrons called photoelectronsare emitted from a metal's surface when light of a certain frequency shines on the surface
🗑
|
||||
| atomic emission spectrum | the set of frequencies of the electromagnetic waves emitted b y atoms of the element
🗑
|
||||
| ground state | lowest allowable energy state of an atom
🗑
|
||||
| de Broglie equation | predicts that all moving particles have wave characteristics.
🗑
|
||||
| Heisenberg uncertainty principle | states that it is fundamentally impossible to know precisely both the veloocity and position of a particle at the same time.
🗑
|
||||
| quantum mechanical model of the atom | the atomic mdel in which electrons are treated as waves
🗑
|
||||
| atomic orbital | three dimensional region around the nucleus that describes the electron's probable location

🗑
|
||||
| aufbau principle | states that each electron occupies the lowest energy orbital available
🗑
|
||||
| Pauli excusion principles | states that a maximum of two electrons may occcupy a single atomic orbital but only if the electrons have opposite signs
🗑
|
||||
| Hund's rule | states that single electrons with the same spin must occupy each equal-energy orbital before additional electrons with opposite spins can occupy the same orbitals.
🗑
|
||||
| valence electrons | the electrons in the atom's outermost orbitals.
🗑
|
||||
| electron dot structure | represents the atomic nuleus and inner-level electrons.
🗑
