Question | Answer |
Visible Light | one type of electromagnetic radiation that moves at a constant speed |
*Velocity of a wave | |
photoelectric effect | emission of electrons from a metal when a light shines in the metal |
quantum | the minimum quantity of energy that can be gained or lost by an atom |
*Planck’s Constant | the constant of proportionality relating the energy of a photon to its frequency |
Photon | particle of electromagnetic radiation that has zero rest mass and carries a quantum of energy |
*Energy of a Photon | |
Ground State | lowest energy state of an atom |
Excited State | state where an atom has a higher potential energy than it has in its ground state |
Line | emission spectrum |
continuous spectrum | emission of a continuous range of frequencies of electromagnetic radiation |
Bohr radius | the radius of the n=1 orbital in hydrogen |
*Interference | |
Heisenberg Uncertainty Principle | in is impossible to determine simultaneously to both the position and vilocity of an electron or any other particle |
Quantum Theory or Quantum Mechanics (same definition for both of these so list them together) | mathmatical description of the wave properties of electrons and other very small particles |
Orbital | 3 |
Quantum numbers | a number that specifies the properties of atomic orbitals and the properties of electrons in orbitals |
Principle Quantum number (n) | quantum number that indicates the main energy level occupied by the electron |
Angular momentum quantum number (l ) | quantum number that indicates the shape of the orbital |
Magnetic quantum number (m) | quantum number that indicates the orientation of an orbital around the nucleus |
Spin quantum number (s) | quantum number that has only 2 values, which indicate the 2 fundamental spin states of an electron in an orbital |
Aufban Principle | an electron occupies the lowest energy orbital that can recieve it |
Electron Configuration | arrangement of electrons in an atom |
Pauli Exclusion Principle | No two electrons in the same atom may have identical sets of four quantum numbers. |
Hund’s Rule | orbitals of equal energy are each occupied by one electron before any orbital is occupied by a second electron,and all electrons in singly occupied orbitals must have the same spin |
Valence Electron | electron that is avalible to be lost gained or shared in the formation of chemical compounds |
Inner | shell electrons |
Highest occupied level | electron containing main energy level with the highest principal quantum number |
Noble Gas Configuration | an outer main energy level, fully occupied in most cases by 8 electrons |
s sublevel or sub | orbital |
*p sublevel or sub | orbital |
*f sublevel or sub | orbital |
orbital | |
Electromagnetic radiation | form of energy that exhibits wavelike behavior as it travels through space |
Electromagnetic spectrum | all the forms of electromagnetic radiation |
Wavelength | distance between corresponding points on adjacent waves |
Frequency | number of waves that pass a given point in a specific time normally one second |
Wavelength | distance between corresponding points on adjacent waves |
