Question | Answer |
---|---|
Continous Spectrum | emission of continous range of frequencies of electro magnetic radiation |
Electromagnetic radiation | a form of energy, that exhibits wavelike behavior as it travels through space. |
Electromagnetic spectrum | all the forms of electromagnetic radiation |
Excited state | a state in which an atom has a higher potential energy than it has its groundstate. |
ground state | the lowest energy state |
line-emission spectrum | a series of wavelenghts of emitted light created when the visible portion of light from excited atoms is shined through |
Photoelectric light | the emission of electrons from a metal when light shines on the metal. |
Quantum | the minimum quantity of energy can be gained or lost by an atom. |
Wavelength | the distance between corresponding points on adjacent waves. |
Angular momentum Quantum # | The quantum number that indicates the shape of the orbital |
Heinseberg Uncertainty Principle | It is impossible to determine simultaneously both the position and velocity of an electron or any other particle. |
Magnetic Quantum # | The quantum # that indicates the orientation of an orbital around the nucleus. |
Orbital | a 3-d region around the nucleus that indicates the probable location of an electron. |
Principal Quantum # | The quantum # that indicates the main energy level occupied by the electron. |
Quantum # | a number that specifies the properties of atomic orbitals and the properties of electrons in orbitals. |
Quantum Theory | a mathematical description of the wave properties of electrons and other very small particles |
Spin quantum # | the quantum # that has only 2 possible values plus 1/2 and minus 1/2, which indicates the 2 fundemental spinstates of electrons in an orbital |
Aufbau Principle | an electron occupies the lowest energy orbital that can recieve it. |
Electron Configuration | the arrangement of electrons in an Atom. |
Highest occupied level | the electron containing main energy level with the highest principle quantum #. |
Hund's Rule | orbitals of equal energy are each occupied by a 2 electron and all electrons insignaly occupied orbitals must have same spin. |
Inner-shell Electrons | an electron that is not in the highest energy level. |
Noble gases | a group of 18 element, helium, Neon, Argon, Cripton, Xenon, and Radion |
Noble Gas configuration | another main energy level fully occupied in most cases by 8 electrons. |
frequency | the # of waves that pass through a given point in a specific time, usually 1 sec. |
Pauli exclusion principle | no 2 electrons in the same atom can have the same set of 4 quantum #'s |
photon | a particle of electromagnetic radiation that has zero rest mass and carries a Quantum of energy. |
