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.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
