electron configuration an address line for an atoms lowest possible energy
Emission shows specific colors of wavelength of light an element gives off
energy the capacity of the wave to do work or produce change
Excited state when electrons absorb some energy and jump to the higher energy levels farther from the nucleus
Frequency the number of wave peaks that pass a given point in 1 second
Ground state when all electrons are in the lowest possible energy state

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.
