TermDefinition
Electromagnetic Radiation Energy that exhibits wavelike behavior and travels through space at the speed of light in a vacuum
Wavelength The distance between two consecutive peaks or troughs in a wave
Frequency The number of waves (cycles) per second that pass a given pint in space
Planck's constant The constant relating the change in energy for a system to the frequency of the electromagnetic radiation absorbed or emitted
Photon A quantum of electromagnetic radiation
Continuous Spectrum A spectrum that exhibits all the wavelengths of visible light
Line Spectrum A spectrum showing only certain discrete wavelengths
Ground State The lowest possible energy state of an atom or molecule
Orbital A specific wave function for an electron in an atom. The square of this function gives the probability distribution for the electron.
Principle quantum number (n) The quantum number relating to the size and energy of an orbital; it can have any positive integer value
Angular momentum quantum number (l) The quantum number relating to the shape of an atomic orbital, which can assume any integral value from 0 to n-1 for each value of n.
Magnetic quantum number (ml) The quantum number relating to the orientation of an orbital in space relative to the other orbitals with the same (l) quantum number. It can have integral values between (l) and -(l) including 0.
Electron spin quantum number A quantum number representing one of the two possible values for the electron spin; either +1/2 or -1/2

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.

To see how well you know the information, try the Quiz or Test activity.
